Abstract

A numerical simulation study is carried out to investigate the influence of bolt tightening process on the distribution of bolt preload force and deformation of linear guide assembly. Firstly, the basic principle of elastic interaction of bolt groups is described and a mathematical characterization model is established. Secondly, the influence of bolt tightening order is analyzed, and it is found that the cross-tightening result is better than the sequential tightening. Finally, the step-by- step tightening strategy of bolts is studied, and the influence of different tightening volume allocation schemes on the residual preload force of bolts and the deformation of the guide rail assembly is analyzed through simulation and comparison of different tightening volume allocation schemes under two-step cross-tightening. The results show that when the guide rail bolts are tightened by two-step cross-tightening and the first step tightening amount is 70%, the consistency of the bolt residual preload is the best, and the maximum deformation of the guide rail is the smallest.
