Abstract

A stationary clearance link algorithm (SCLA) for calculating the reaction-force of revolute clearance joints in crank slider mechanisms is proposed in this paper. The SCLA is more efficient than other algorithms of the same accuracy. Furthermore, based on the Winkler foundation model, an unsymmetrical Winkler foundation model and a double elastic layer Winkler model are proposed. By integrating a dynamic model and the unsymmetrical Winkler foundation model with Archard wear model, an improved integrated wear prediction model is also generated. A series of experiments have been performed to compare with the predicted analysis data, and the results showed a good agreement. As a real industry application, with the double elastic layer Winkler model, the integrated wear prediction model was successfully used to predict the wear depth of the joint bearing (bimetallic bearing) for the cantilever crane of a concrete pump truck of Sany Heavy Industry.
