A Prediction Model for Equivalent Parameters of Rolling Guide's Joint

Abstract

To obtain a prediction model of the equivalent parameters of rolling guide's joint, an F-P-KC prediction model was established based on force, pressure and equivalent parameters. Firstly, according to the linear assumption of physical parameters within the rated range, an F-P model was established in the consideration of the loads, types and installing modes of guide’s slider group; secondly, a P-KC model was established in terms of the result of the media condition of joint surface; finally, the prediction model was successfully applied in the project, and the feasibility was verified. A new effective way for solving the similar problem is opened up by the model and it also lays a theoretical foundation for the following study of dynamic characteristics.
