Study on Simulation and Experiment of Dynamic Characteristics of the Linear Rolling Guide in Turn-Milling Centre

The Linear Rolling Guide that springs and damping units imitate joints is simulated by finite element methods to analyze accurately the dynamic characteristics of Linear Rolling Guide during the design stage. The proposed method can predict the regular pattern which joint stiffness and joint span affect natural frequency and harmonic response. The research demonstrates that the method predicts well the dynamic characteristics of the Linear Rolling Guide, therefore, the simulation method is feasible by experimental verification, which provides reference for dynamic optimal design Linear Rolling Guide in turn-milling center.
