A new model for the preload degradation of linear rolling guide

Chang-Guang Zhou et al.

Summary: A preload degradation model for LRG was proposed and experimentally verified, showing that factors such as external load, running speed, and fractal parameters affect the rate of preload loss. The numerical simulation results indicated the varying degrees of influence these factors have on the rate of preload loss in linear rolling guides.

An improved model for meshing characteristics analysis of spur gears considering fractal surface contact and friction

Zhifang Zhao et al.

Summary: The establishment of a fractal contact model for gear pair contact allows for the calculation of contact stiffness and compliance. Numerical simulation results show that contact stiffness increases with fractal dimension, while factors such as changes in fractal parameter and friction coefficient affect mesh characteristics.

A time-dependent dynamic model for ball passage vibration analysis of recirculation ball screw mechanism

Mengtao Xu et al.

Summary: A general time-dependent dynamic model for describing ball motion and axial periodic micro fluctuation within a ball screw subjected to external load is proposed in this study. The effects of applied load, preload, and screw rotational speed on dynamic response are discussed theoretically, and reducing vibration amplitude is suggested through small ball diameter and phase difference between ball groupings. The proposed model is experimentally validated.

A comprehensive nonlinear dynamic model for ball screw feed system with rolling joint characteristics

Mengtao Xu et al.

Summary: This paper introduces a dynamic model of a ball screw feed system, focusing on the dynamic characteristics of the worktable under combined loads. The study shows that nonlinear joints and coupling effects lead to rich and diverse nonlinear phenomena in the worktable response, with nonlinear behavior significantly influenced by changes in excitation, platform position, screw length, preload, and damping.
