摘要
轻量化是机构优化设计的重要部分,在满足刚度与良好动态特性前提下,进行合理的厚度优化具有积极的意义。模态分析可以为振动工作平台的性能评估提供了一个强有力的工具,依据可靠的分析及实验,能获得有效的性能评估指标。本文借助ANSYS有限元理论对PA66/GF30振动工作台进行模态分析,得到设计机构的固有频率和固有振型,通过模态分析法来对机构进行动态性能分析,验算其结构设计能否达到总体设计要求,并对设计的振动工作平台厚度进行优化。
Lightweight is an important part of structural optimization design, it is of great significance to optimize the thickness under the premise of satisfying the stiffness and good dynamic characteristics. The modal analysis can provide a powerful tool for the performance evaluation of the vibration platform, and can obtain the effective performance evaluation index based on the reliable analysis and experiment. ANSYS finite element theory on PA66/GF30 vibration table modal analysis is carried out with the help of design institutions inherent frequencies and vibration modes of the modal analysis method of mechanism dynamic performance analysis, checking the structure design can meet the requirements of the overall design, and the design of the vibration platform thickness is optimized.
