摘要:
在考虑构件弹性小变形的机构动力学有限元分析中 ,某些构件的弹性特性对动力学过程影响很小 ,因此可以作为刚体单元来处理。该文对这种刚体单元作了详细的描述 ,建立了其质量矩阵和刚度矩阵。这种单元可以作为考虑构件弹性变形的机构动力学有限元法的单元库中的一种基本单元 ,用于模拟机构系统中的刚性构件
Abstract:
In the dynamic analysis o f elast ic mechanisms w ith small elastic deformat ion by f inite element metho d, the elast ic characterist ics of some component s hav e lit tle effect on the dy namic processes o f mechanism sy stems, so these component s can be processed as a kind of rigid elements. T his paper describes the rig id element , and builds it s mass mat rix and stif fness matr ix . The r ig id element can be used as a basic element ty pe of the element library fo r the elast ic mechanism dynamic analy sis by FEM, to simulate the rigid compo nents in mechanism systems.
