Key words: plastic gear steel gear gun modal analysis of vibration characteristics 0 Introduction The gear drive is the most important in the mechanical transmission drive gear transmission because of its high efficiency, compact structure, the transmission ratio stable and are widely used in engineering. Accelerated due to the development of high-performance engineering plastics, the proportion of the application process for plastic and steel, plastics in the field of mechanical engineering is increasing, the production of gear materials are no longer limited to metallic materials, has grown to the plastic gear. On the application and theoretical study of the plastic gears, and steel gear, late research time is also shorter, and domestic and foreign researchers on the understanding of the plastic gear performance and application very immature, but to imitate and improve ['] on the basis of the steel gear. Therefore, the experimental study of plastic gear is necessary. Plastic material with Bo, the elastic energy, and thus has obvious noise reduction and vibration damping performance. In fact, for the transmission of power in terms of gear when the gear body's natural frequencies and the frequency of exciting force is very close to the even drill the plastic material gear also have a resonance and noise [[2}}} 4321-437A. Therefore, during the plastic gear design, the vibration characteristics of the study is necessary. We use ANSYS software to gear finite element model, modal analysis, mode shapes and natural frequency of the plastic gears and alloy gear to provide a basis for the structural design and optimization of gear. 1 A gear modal analysis Modal analysis is used to determine the natural frequency of the vibration characteristics of structures or machine parts in the design and mode shapes. Withstand dynamic bearing load structure design parameters [3] 4321-4324. Finite element analysis software ANSYS, modal analysis is a linear analysis of prestressed structure and cyclic symmetry structure modal analysis, modal analysis process is divided into four steps: modeling, loading and solving, extended modal and results post-processing. 1.1 gear finite element model ANSYS provides three kinds of ways: to generate a model generation method with ANSYS to create solid model, the model established by the input model system. The direct generation method suitable for small, simple model, the leaders of the other systems if the model is not suitable for meshing, requires a lot of repair work. Gear model is relatively complex, suitable for solid modeling method. Known by the finite element theory, the solid model can not be directly used for finite element calculation, so take it mesh to generate a finite element model, the mesh will directly affect the accuracy of the finite element calculation results .

机械设计的有限元分析及结构优化

机械设计的有限元分析及结构优化

机械设计的有限元分析及结构优化摘要：有限元分析是机械设计中重要的工具，能够模拟材料和结构，通过将复杂的实际结构，离散成有限数量的元素，并利用数值计算方法，评估结构的各方面性能。

但是，进行有限元分析，并不能保证最优的设计，因此需要进行结构优化。

通过调整设计参数，寻找最佳的几何形状或材料分布，以满足给定的性能指标和约束条件。

基于此，探讨有限元分析和结构优化的相关内容，提出了以下观点，仅供参考。

关键词：机械设计；有限元分析；结构优化引言：有限元分析是一种重要的数值仿真方法，通过将复杂结构，离散为有限数量的小单元，可以对其进行力学行为和性能的模拟与评估。

结构优化则旨在通过调整材料、形状和布局等参数，以最大限度地提高结构的性能和效率。

有限元分析技术，在机械设计中的应用，涵盖材料力学、热力学、流体力学等方面的问题，因此需要进行深入的研究，以促进机械设计的发展和创新。

一、项目概况某公司是一家制造工程设备的企业，正在开发一种新型的机械设计。

为了确保该机械设计在使用过程中的安全性、可靠性和效率，最后决定利用有限元分析和结构优化，来进行设计验证和改进。

通过有限元分析软件对新型的机械设计，进行模拟和分析，以评估其在不同情况下的变化数据。

这可以帮助确定机械设计构中的薄弱点和缺陷，并指导后续的优化工作。

二、机械结构静力学分析（一）有限元方法运用有限元方法通过将结构离散化为许多小的单元，对每个单元进行分析，并将其连接起来形成整体结构，来研究机械结构的力学行为。

有限元方法的关键步骤包括以下几个方面：第一，将机械结构离散化为许多小的单元，以便更好地进行分析。

这些单元可以是三角形、四边形或其他形状的网格单元。

第二，在进行离散化后，需要选择适当的位移插值函数，来描述每个单元内部的位移变化。

常见的插值函数有线性插值函数和二次插值函数等。

第三，利用所选的位移插值函数，可以通过解决每个单元内部的应力方程，来计算单元的力学特性，如应力、应变和变形等。

基于SOLIDWORKS的齿轮参数化实体模型设计毕业设计(论文)

摘要渐开线齿轮由于能保证特定传动比、受力方向不变等优点，而广泛应用于各种通用机械中，但因其齿廓形状和轮体结构复杂多变而成为三维造型技术的难点。

常规齿轮设计过程烦琐：齿轮轮廓线的生成需要大量的计算过程；轮廓线的绘制，需要通过关系式控制；齿轮种类较多，不同类别绘制方法不同。

本论文主要论述了基于SOLIDWORKS开发平台，进行齿轮参数化实体模型设计的过程，应用其工具包开发了齿轮参数化设计系统，通过创建的对话框修改齿轮参数，例如模数、齿数、齿宽、压力角、变位系数等，可以得到相应的渐开线齿轮，从而满足设计要求。

实际应用表明该系统可以大幅度提高工作效率。

该系统的建立方法亦可应用于其他零件的参数化设计关键词：SOLIDWORKS；齿轮；参数化设计；建模AbstractInvolute gear due to the difficulty to ensure specific transmission ratio, the force direction constant, etc., are widely used in a variety of general machinery, but because of its complex and changing the shape of the tooth profile and wheel structure a three-dimensional modeling techniques. There are some inefficient aspects in gear design, such as a lot of work should be needed in process of getting the gear profile; it is hard to draw the gear profile without equation; Different kind of gear needs several kinds of methods to build.
