【Abstract】 The experimental method to measure the stiffness and damping coefficients of rolling guide is put forward. By constituting uncoupling model with one degree of freedom of experimental system, the influence of the accessorial structure on the experimental system is eliminated, and the experiment data of rigidity and damping with high precision are obtained. The method can be used to measure the stiffness and damping coefficients in upright direction as well as in side direction of rolling guide ,and full mechanical properties of rolling guide can be obtained, which is of significance for analysis of mechanical behavior of whole structure of NC machine tool.更多还原
