| Abstract: | In the dynamic design of the high speed and high precision 5 axes gantry machining center, the contact parameters of guide surface had been acquired by the dynamic test and they had been applied to the numerical simulation model. By this way, the accuracy of model was improved. In the structure dynamic design, a simulation method combining rigid body and flexible body is applied. The main components are set to flexible, and their influences are analyzed. The structure optimizations are made to improved the dynamics of the machine on these analyses. |
