Abstract
Linear rolling guides are widely used in the NC machine tool, and usually the NC machine tool's characteristics shall been influenced by the characteristics of the guide greatly. The HSR series of liner rolling guides are taken as the research object of the paper. The methods of constructing the dynamic finite element analysis models are studied. The contact element is applied to simulate the characteristics of junction surfaces during the static characteristic analysis. The spring damping element is applied during the dynamic characteristic analysis. The static stiffness, natural frequencies, modal shapes and other characteristics are obtained by finite element analysis. Then the experiments of linear rolling guide are carried out and verified the model that had been built and calculation results of finite element analysis.
