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. | | 查看全文查看/发表评论下载PDF阅读器 | |
