Presliding friction mode: modelling and experimental study with a ball-screw-driven set-up

摘要

To cope with the increasing high precision requirement in many applications of ball-screw-driven stages, system dynamic behaviour under friction force should be carefully investigated, especially in the presliding friction regime. Presliding friction has many special characteristics such as elasticity, hysteresis with memory and plasticity. In this paper, dynamic modelling of a ball-screw-driven stage under presliding friction is experimentally investigated. The model is then validated by the consistency of results in experiments and simulations. Despite the complex structure of the system and the complicated nature of friction, the system can be described by a set of nonlinear state equations.
