实验六动平衡综合实验一：曲柄导杆滑块机构运动参数测定实验报告专业班级姓名实验时间一、实验目的1.组装实验用曲柄导杆滑块机构，通过组装，加深对机构组成的认识；2.滑块的位移、速度、加速度检测；3.连杆上点的运动轨迹分析；4.改变机构构件的杆长和位置，进行滑块运动规律的实测与仿真，了解速度波动的影响和机构急回特性。
二、仪器设备THMCM-1型曲柄导杆滑块凸轮测试实验装置实验原理简要(请自行节选)三、三、实验原理简要(一)实验装置电源仪表控制部分操作说明本实验台由电源仪表控制部分和机械部分两部分组成。
电源仪表控制部分包括电源总开关（即漏电保护器）、电源开关（大黑开关）、一只指针式电压表、一只指针式电流表、调速器和传感器接口。
1.实验前先将实验台左后侧的单相电源线插头与实验室内电源接通。
在电源接通前应使漏电保护器处于关的位置；电源开关（大黑开关）处于“关”状态；电动机调速器的开关打到“STOP”位置，调节旋钮逆时针旋置最小。
2.实验台左侧的漏电保护器是整个实验台的电源总开关，打开漏电保护器，使电源开关（大黑开关）打到“开”的方向，电源开关（大黑开关）自身点亮，电机调速器的指示灯亮，指针式电压表有指示。
3.指针式电流表显示电动机的工作电流，使电动机调速器的开关打到“RUN”位置，慢慢的顺时针旋转调节旋钮，电动机缓慢转动，指针式电流表有指示。
4.实验台面板右边是传感器接口部分，使传感器上的插头与面板上的插座芯数相同的插在一起，把传感器的数据传送给采集板。
（二）实验装置的结构特点本实验台的机械部分，主要由交流减速电机、金加工、传感器等组成。
直流电机作为动力装置，通过三角带带动盘形凸轮转动。
本实验装置可组成的4种实验机构中，大多数零部件都是通用的，只需要拆装少量零部件即可实现机构转换。
每一种机构的某些参数，如曲柄长度、连杆长度、凸轮机构的偏距等都可以在一定范围内调整，学生可通过调整参数改变机构的运动参数。
实验机构安装在铝合金型材架上；有杆构件长度及滑块偏心距均可进行无级调节，分析该参数改变，对机构运动特性的影响。
