In order to reduce or avoid the tedious experiment for the dynamics modeling of the linear rolling guideway, a general finite element modeling approach is presented. Firstly, the contact characteristic between a single ball and groove is analyzed, and the relative contact stiffness of single ball is determined under different preload levels. Next, using the spring-mass elements to simulate the contact of single ball and groove, and the precise finite element model is created on the basis of considering the distribution of the balls. The detailed procedure and key steps of creating the precise finite element mode are introduced. At last, the SHS-35R guideway produced by THK Corporation is chosen as study object, and its nature characteristics are obtained. The analysis results are found identical with the analytical solution, which proves the proposed approach is correct.
