Influence of Non-ideal Boundary Constraints on Kinetostatic Behaviors of Compliant Bistable Mechanisms
Bistable mechanisms can maintain two distinct positions without energy assumption,which made them widely used in many special situations.The performance of bistable mechanisms may suffer from its non-ideal boundary conditions(the deformation of its ostensibly rigid frame),which may even incapacitate the bistability of the mechanisms.To capture the influence of non-ideal boundary conditions on the behaviors of the mechanisms,a kinetostatic model for bistable mechanisms is presented in this paper.In the model,behaviors of both the frame and flexible beams are considered and characterized through the Chained Beam Constraint Model(CBCM).Three cases are modeled and analyzed to show the effectiveness of the model.The results are validated by the finite element analysis as well as experiments.
