Partially compliant spatial slider–crank (RSSP) mechanism

In this study, a novel compliant mechanism, “partially compliant spatial slider–crank (RSSP)” is proposed. All possible configurations of compliant RSSP mechanisms are classified and discussed. A method is derived to determine deflection of the multiple-axis flexural hinge for all positions of the crank. A design procedure for partially compliant RSSP mechanisms is introduced. In order to prove the feasibility of the proposed mathematical model, a real model is built and it is shown that results are consistent.

► Partially compliant spatial slider–crank (RSSP) is proposed.
