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.
