摘　　要：在大型高架桥式、高速、高精度五坐标龙门加工中心的动态设计中,通过动态测试的方法获得导轨结合面的特性参数,并将其应用到数字仿真模型中,提高模型的精度。在结构动态分析中采用刚体与柔性体结合的仿真方法,对加工中心的关键部件进行柔性化,分析其对系统相应的影响,并在此基础上对这些主要部件进行结构优化设计,提高系统的动态特性。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.
