Abstract

Linear rolling guideways are widely used in precision mechanical systems such as robots and machine tools. Clarifying the natural vibration characteristics of a linear rolling guideway is important for improving the performance of mechanical systems, because the dynamic characteristics of the guideway strongly influence the dynamics and posture accuracy of mechanical systems. This study focuses on the natural vibration characteristics of linear rolling guideways. We discuss both the nonlinear relationship between friction and natural vibration, and the influence of the lubricant specification on the nonlinearity of nonlinear natural vibration. Additionally, the effects of the lubricant specifications on the damping ratio are different for different vibration modes, owing to the differences between the damping mechanisms.
