Version V06.20.39.02 is recommended.• A new installation can be carried out using the NCU service system and VNC Viewer (AccessMyMachine /P2P).•The description of the procedure can be found in the installation manual (SINUMERIK ONE New installation and upgrade) published in SIEMENS Industry Online Support.•Upgrading with Create MyConfig 6.1 is not released•The MCU1720 must have at least the InitNCU image version 06.00.38.004.2Installing the NCU service system on a USB stickInstall the service stick image using tool "AccessMyMachine /P2P" from V4.8 HF2 and higher using menu item «Tools – write image to CF card».Installing on MCU1720:•After the installation has been completed, remove the USB stick from the PG/PC and boot an MCU 1720 one time from this stick. The USB stick can be inserted in one of the two USB ports (X125, X135) of the MCU1720. To do this, the NCK rotary switch of the MCU1720 must be set to >< 0. This boot process takes a little bit longer; a "P" in the 7-segment display of the MCU indicates that the FAT partition of the images on the USB stick is adapted. The 7-segment display goes dark after partitioning has been completed.•Afterwards, reinsert the stick into the PG / PC. Under Windows, you can now see an empty USB stick. You can see the installed version of the NCU service system in file "eboot_version.txt". Now copy the required CNC software (file with extension .tgz) to this stick.•Now insert the USB stick into one of the two USB ports (X125, X135) and switch on the MCU1720 again (NCK rotary switch of the MCU1720 >< 0)•The MCU1720 is now rebooted from this USB stick. This is indicated as the 7-segment display is dark. The NCU service system is called from the PG/PC using program "VNC Viewer AccessMyMachine /P2P" via interface X127. Set theinterface properties to "Automatically obtain IP address".•USB Stick 6AV6881-0AS42-0AA0 "USB-Flash Drive, 32 GB, USB3.0" is recommended.4.3Installing the CNC software4.3.1Upgrading the firmwareTo do this, at the PG/PC, the files required must be copied to the service stick.After this, the MCU 1720 is booted from the service stick:Select menu item «Firmware Update»:Depending on the firmware update type, acknowledge the corresponding menu item with «OK», and follow the other instructions.4.3.2Upgrading the NCU system softwareTo do this, at the PG/PC, the files required must be copied to the service stick.After this, the MCU 1720 is booted from the service stick:Select menu item «Update NCU Software and Data»:Select the appropriate menu item corresponding to the update type:Select the desired SW package (.tgz) and confirm with «OK».Updated completed:5NOTES AND RESTRICTIONS5.1General notes/restrictions•Only an HMI base can be started on the MCU1720. This means that an HMI 3GL application and the SINUMERIK commissioning tool cannot be simultaneously started.•Distributed NCK I/O connected to PROFINETDistributed NCK I/O (IOs, drives) are only supported at the X150. This means- Isochronous NCK drives such as CU320-2 PN can only be operated at the PROFINET PN1 interface (X150).- NCK I/O such as ET200SP PN can only be operated at the PROFINET PN1 interface (X150).Access from NCK to PROFINET I/O/drives is only supported up to PROFINET device number 126.•Control loop optimization (tuning) S210 must be performed manually without SINUMERIK ONE Commissioning Tool support•PLC setup archiveIf a PLC setup user archive is imported, this corresponds to transferring the CPU folder with all run-relevant objects and the hardware configuration.The CPU compares the content of the configuration on the SIMATIC memory card with the backed-up retentive data.If the backed-up retentive data matches the data of the configuration on the SIMATIC memory card, then theretentive data is retained.If this data differs, the CPU automatically triggers a general reset (i.e. the retentive data is deleted).•TIA Portal functionality web serverAccess to the PLC web server via interfaces X127/X130 is not possible using the HTTPS protocol. Only HTTP issupported.Use interfaces X150/X160 when using HTTPS.•CA Eco (Protect MyMachine /3D Primitives and Protect MyMachine /3D Primitives, 1 add. channel) The CA Eco function together with an IPO clock of 2ms is currently not supported.When activating the options "Protect MyMachine /3D Primitives - 6FC5800-0CS03-0Yx0 / Protect MyMachine /3D Primitives, zus. 1 channel - 6FC5800-0CE00-0Yx0" a new CA algorithm is automatically activated.The IPO load will be higher due to the new CA algorithm.Collision avoidance is a computationally intensive function and is therefore not released with the "Fast Interpolation Cycle" option.Depending on the collision model used and computationally intensive NC functions, it may happen that the collision checks cannot be completed in time. In this case, the collision protection is limited and alarm 26303 "Collision check incomplete" is issued. This alarm can be suppressed by the machine manufacturer (MD11415$MN_SUPRESS_ALARM_MASK_2 bit 29).Technology G-code groups 59 must be set correctly (DYNNORM, DYNPOS, DYNROUGH, DYNSEMFIN, DYNFINISH,DYNPREC).Collision avoidance uses the emergency brake ramp in exceptional cases (alarm 26285). The followingmachine data must be checked and set sensibly:MD36610 $MA_AX_EMERGENCY_STOP_TIMEMD36620 $MA_SERVO_DISABLE_DELAY_TIMEIf alarm 26285 occurs, it may happen that you have to switch off collision avoidance for free driving via the HMI Operate.•In the case of alarm 26280 in the JOG, reset must be activated before free driving.•Program listsProcessing of program lists via PLC-NC interface (DB19) with Commissioning Tool is currently not supported.•Manual reading of a data backup created in V1.14 using TEA fileWhen manually importing a data backup created in V1.14 using TEA files, the following reset alarm occurs: "1 error in GUD, macro or INI file".After charging, the operator is also prompted to trigger an NCK reset and after this the alarm is gone and thecontroller is back to normal.The general reading of the data backup and the adjustment of the remaining MDs is not affected.When loading the archive, the alarm is also not noticeable, as a reset is triggered when the NCK is loaded anyway.•General recommendation for the use of USB sticks at SINUMERIK-Operate/ SINUMERIK ONE Commissioning Tool After data has been copied to the stick or changes have been made to files on the stick, a short waiting time (about 20 seconds) should be observed before the stick is removed.•Sinumerik Tuning CenterSINUMERIK Operate ONE / SINUMERIK ONE Commissioning is not supported in Version 1.0Safety-relevant notes for the TIA Portal web server- Activating the web server in STEP 7Activating the web server reduces the level of protection against unauthorized access to functions and data of this device from the outside and via the network.When accepting projects from suppliers, in which the web server is already activated and configured on the board, this safety note is not displayed.- Setting up the user administrationIn STEP 7, in the area "Web server > User administration" you must extend the user list.The user list offers you the following options:- Create users- Define access rights- Assign passwordsNewly created users only have options available to them where the access rights have been specifically assigned.If you are user that has not logged in, then you access the web server as user "Anyone". User rights should not be assigned to user "Anyone".5.2Notes regarding the CNC softwarePassword guidelines:When an NC password is changed, the password for the respective Linux account is also changed.i.e. when the manufacturer's password is changed, the password for the Linux account "manufact" is also changed.IMPORTANT: After one of the existing NC passwords (e.g. SUNRISE) has been changed, it is no longer possible tochange back to the old password, as it does not correspond to the new guidelines (minimum length 8 characters,uppercase letter, lowercase letter, number).Notice:If an access level in NCK is to be set by the PLC via FB4 (PI-Service_N_LOGIN), a password that is used for the NCK (and simultaneously for Linux) must be precisely 8 characters long.This scenario must be taken into consideration when assigning new passwords. Otherwise, passwords can be 8 - 32 characters long.The passwords for the NCK and the corresponding Linux accounts of the NCU basic system are now changed with the "Change password" SINUMERIK ONE Commissioning Tool dialog.5.3Notes regarding SINUMERIK MC STEP7 ToolboxSINUMERIK MC STEP7 Toolbox V17 must be used.This toolbox can be used to engineer SINUMERIK MC hardware.The software is an option package for SIMATIC TIA Portal V17The following hardware is supported:•MCU1720 V1.13, V1.14, V1.15Supported functions:•Creating a hardware configuration•Configuring the S7-1500 PLC•Support of Safety Integrated•SINUMERIK DSF archive hardware/software with alarm texts•Creating NC tags via NC tag accessUnsupported functions:•Function "Restore factory settings" via SIMATIC TIA Portal V17 is not supported.•Uploading the PLC project from the MCU1720 is not supported.5.4Information regarding the use of TIA Portal StartdriveTIA Portal Startdrive V17 must be used.5.5Information regarding SINUMERIK BaseSoftwareSINUMERIK Base Software V14.0 SP2 HF4 should be used.By installing SINUMERIK BaseSoftware, the IP address of the internal "Intel® l210 Gigabit Backplane Connection" interface is set to the default value.5.6Information regarding SINUMERIK ONE CommissioningSINUMERIK ONE Commissioning V6.15 SP2 HF2 should be used.•Connection to the NC/PLCIn order that in "SINUMERIK ONE Commissioning" a connection can be established to the NC/PLC, a correct network adapter (Gigabit Backplane Connection TCPIP.1) must be manually set in access point S7ONLINE and SINUMERIK.Otherwise, alarm 150202 is displayed at the HMI.It can be performed using the "Siemens Communication Settings"tool.•Manufacturer, PLC alarmsIt is not possible to edit/create manufacturer PLC alarms using the "Edit alarm texts" screen form.Workaround: Create alarm and message texts using alarm text files. Refer to the "SINUMERIK Operate“ IM9Commissioning Manual, Chapter 13•Areas/softkeysFor the MCU1720, the following areas/softkeys were removed/disabled:- Diagnostics >> ">" >> TCP/IP Diag. >> SK "MCP"- Diagnostics >> ">" >> TCP/IP Diag. >> SK "TCU"- Commissioning >> HMI >> SK "Ctrl-Energy"- Commissioning >> ">" >> Networks >> SK "OPC-UA"- Diagnostics >> SK "Remote Diag"- Commissioning >> NC >> PROFIBUS >> SK "DP Integrated"- Commissioning >> NC >> PROFIBUS >> SK "DP X126"- Commissioning >> NC >> PROFIBUS >> SK "DP X136"•Program listsProcessing of program lists via PLC-NC interface (DB19) with Commissioning Tool is currently not supported.•IBN-archive factory setting of this machineCreating an IBN archive "Factory setting of this machine" is currently not supported with the Commissioning Tool.•Machine registrationThe registration of the machine via the SINUMERIK ONE Commissioning Tool is currently not supported.5.7Information regarding SINUMERIK Integrate Create MyHMI /3GL•The HMI base of SINUMERIK ONE, included in "SINUMERIK Integrate Create MyHMI /3GL", should be used for the MCU1720•The ToolManagment service has not been released•The infrastructure service has not been releasedFor additional information, see the manual for the "SINUMERIK Integrate Create MyHMI /3GL" programming package5.8Drive ‚NC Extend‘ for EESPreparation1.On the IPC in Windows (Explorer) set up drive sharing for directoryC:/Programme(x86)/Siemens/SinumerikCommissioning/user/sinumerik/data/prog.

钢筋混凝土原理和分析 思考与练习1.基本力学性能1-1混凝土凝固后承受外力作用时,由于粗骨料和水泥砂浆的体积比、形状、排列的随机性,弹性模量值不同,界面接触条件各异等原因,即使作用的应力完全均匀,混凝土内也将产生不均匀的空间微观应力场。
在应力的长期作用下,水泥砂浆和粗骨料的徐变差使混凝土内部发生应力重分布,粗骨料将承受更大的压应力。
在水泥的水化作用进行时,水泥浆失水收缩变形远大于粗骨料,此收缩变形差使粗骨料受压,砂浆受拉,和其它应力分布。
这些应力场在截面上的合力为零,但局部应力可能很大,以至在骨料界面产生微裂缝。
粗骨料和水泥砂浆的热工性能(如线膨胀系数)的差别,使得当混凝土中水泥产生水化热或环境温度变化时,两者的温度变形差受到相互约束而形成温度应力场。
由于混凝土是热惰性材料,温度梯度大而加重了温度应力。
环境温度和湿度的变化,在混凝土内部形成变化的不均匀的温度场和湿度场,影响水泥水化作用的速度和水分的散发速度,产生相应的应力场和变形场,促使内部微裂缝的发展,甚至形成表面宏观裂缝。
混凝土在应力的持续作用下,因水泥凝胶体的粘性流动和内部微裂缝的开展而产生的徐变与时俱增,使混凝土的变形加大,长期强度降低。
另外,混凝土内部有不可避免的初始气孔和缝隙,其尖端附近因收缩、温湿度变化、徐变或应力作用都会形成局部应力集中区,其应力分布更复杂,应力值更高。
1-2解:若要获得受压应力-应变全曲线的下降段,试验装置的总线刚度应超过试件下降段的最大线刚度。
采用式(1-6)的分段曲线方程,则下降段的方程为:20.8(1)xy x x=-+ ,其中c y f σ= p x εε= ,1x ≥ 混凝土的切线模量d d d d cct pf y E x σεε==⋅ 考虑切线模量的最大值,即d d yx的最大值: 222222d 0.8(1)(1.60.6)0.8(1) , 1d [0.8(1)][0.8(1)]y x x x x x x x x x x x -+----==≥-+-+令22d 0d yx =,即:223221.6(1)(1.60.6) 1.60[0.8(1)][0.8(1)]x x x x x x x ---=-+-+ 221.6(1)(1.60.6) 1.6[0.8(1)]x x x x x ∴--=-+整理得:30.8 2.40.60 , 1x x x -+=≥ ;解得: 1.59x ≈222max 1.59d d 0.8(1.591)0.35d d [0.8(1.591) 1.59]x y y x x=-⨯-⎛⎫===- ⎪⨯-+⎝⎭ 2,max 3max max d d 260.355687.5N/mm d d 1.610c ct p f y E x σεε-⎛⎫⎛⎫∴==⋅=⨯= ⎪ ⎪⨯⎝⎭⎝⎭ 试件下降段的最大线刚度为:222,max 100mm 5687.5N/mm 189.58kN/mm >150kN/mm 300mmct A E L ⋅=⨯= 所以试件下降段最大线刚度超过装置的总线刚度,因而不能获得受压应力-应变全曲线(下降段)。

The Edison British Style semiconductor protection fuses include a 660VAC line utilizing new filler technology. These new fuses have greatly reduced peak let-through current and energy under fault conditions and hence extend fuse protection capability. They can be recognized by the letter “F” in their catalog number. Application and technical data for these 660VAC “F” fuses and the original line of 240VAC British “T” type fuses are presented on the following pages.
“F” Range
This is a superior design of fuses in the same physical package as the “T” range.
Equivalent Ratings
This table shows the suggested equivalent ratings to replace a “T” with an “F”.
Because of the new design technology it has been possible to obtain the equivalent energy let-through I 2t with a higher amp rated fuse hence reducing the possibility of premature operation.
This table gives a range of suggested acceptable new “F”type to replace the earlier “T” type.
To upgrade your protection to the new “F” series select a fuse rating within the range shown that suits your circuit inrush requirements.You will still have the same or better protection of your semiconductor devices.
It should be remembered that to protect devices we must consider the energy let-through of the selected fuse. The label amp rating will relate to the full load current and the circuit inrush amps.
The suggested replacements are based on:
a.Similar surge withstand to normal circuit overloads.
b.Lower total I 2t let-through.
This gives enhanced reliability due to the use of a higher current rated fuse which avoids nuisance operation and still gives improved short-circuit protection.
