摘要
在讨论基于有限元法(FEM)的变量化设计技术及其在静、动态结构设计中应用的基础上,给出了结构准静态特性和变量化设计的概念.用准静态变量化优化设计方法对一液压机械结构进行了实例研究,提出了通过变量化动态优化元结构提高整机结构的动态特性.最后,探讨了机械动态优化设计的一般原则和方法.
On the basis of variational design technology based on FEM and its application in static and dynamic structure designs, the concepts of structural quasi-static property and variational design were stated, and as an example, the structure of a hydraulic machine was optimized using the quasi-static variational optimization design. In addition, the method of improving its dynamic properties by the dynamic optimization of element structures was proposed. Finally, the general principle and method of dynamic optimization design of mechanical structures were discussed.
