Abstract: Compliant
mechanisms gain some or all of their mobility of their members rather
than from rigid-body joints only. So the deflections of their members
are large, and the geometrically nonlinearity is introduced in the
governing equations. It is important to develop the efficient and usable
analysis and design techniques. Based on the multi-rigid-body discrete
element model, the model method for compliant segment and compliant
mechanisms is developed, and the governing equations are deduced. It is
applicable to the eigenfrequency and geometric nonlinear response
analysis of compliant mechanisms. Given examples show that the model is
successful in static and dynamic geometric nonlinear analysis of
compliant mechanisms.
