Stationary clearance link algorithm for solving the counter-force in the clearance revolute joint of crank slider system

To accurately predict the performance of mechanisms with clearance joint and estimate its life, it is very critical to efficiently and accurately calculate the counter-force in the clearance revolute joint. In this paper, an independent and efficient algorithm, stationary clearance link algorithm, was proposed to calculate the force in the clearance bearing of crank slider system based on a clearance revolute joint model. Differing from Li's simplified algorithm based on the force in the ideal revolute joint, the stationary clearance link algorithm is only based on a clearance revolute joint model, it is not necessary to solve the reaction-force in the ideal revolute joint and nonlinear equation group. Initializing the stationary clearance link and simplifying the clearance counter-force in the clearance model, the practical clearance counter-force could be obtained by using the stationary clearance link algorithm with more efficient than Li's method. At the end, the feasibility and high-efficiency of the stationary clearance link algorithm are demonstrated by an example.
