| Abstract: | Through the force analysis of rolling linear guide, and based on Hertz contact theory, a dynamic model of the linearrolling guide was established with consideration of the nonlinear stiffness; the ansys finite element analysis was carried out onthe guide rail, and the modal shape and natural frequency were found out, and the influence that different fixed ways work onits dynamic characteristics was studied, and finally some useful conclusions were obtained in this paper, thus a certain refer-ence to the engineering practice was provided. |
