Dynamic modeling of a slider-crank mechanism with coupler and joint flexibility
Mechanism and Machine Theory, 1994 Abstract Modeling and dynamic analysis of a slider-crank mechanism with flexible joint and coupler is presented. The equations of motion of the mechanism are formulated using a newly evolving multibody formalism and cast in terms of a minimum set of generalized coordinates through a Jacobian matrix expansion.

A Dynamic Analysis of the Plane Crank-and-Rocker Mechanisms with Clearances
Bulletin of JSME, 1980 The equations of motion of the plane four-bar mechanisms have been derived for all of possible numbers and positions of clearance-connections except the input-shaft position when the mechanisms rotate at constant speeds in a vertical plane. Applying the equations to a crank-and-rocker mechanism, the effects of the numbers and positions of clearance ...
