The static and dynamic characteristics of the beam of a gantry-type machining center are analyzed by means of ADAMS and ANSYS. Considering effect of gravity and cutting forces, the static deformation of the beam is obtained after calculating the interacting forces between the guide and the slide block by ADAMS. Moreover, the contact parameters of the guide surface are acquired by dynamic tests and parameter identification, then they are applied to the simulation model of the beam-slide box system, whose natural frequencies and modal shapes are achieved by modal analysis. Furthermore, the effect of changes of the contact parameters on the dynamic behavior of the beam-slide box system is also investigated.
