对振动台关键部件建模后,获得了包括动圈、扩展头、滑板、加强板、牛头等部件的较为准确的有限元模型。针对某卫星模型与振动台模型集成后的组合模型进行了有限元振动响应计算。将虚拟试验结果与实际试验结果、卫星传统仿真结果进行对比,通过分析卫星频率及响应量级来评价虚拟振动试验对卫星研制的意义。 After modeling the key components of vibrating table, a more accurate finite element model including dynamic ring, extension head, skateboard, stiffener and Ngau Tau was obtained. The finite element vibration response calculation is carried out for a combined model of a satellite model and a shaking table model. The virtual test results are compared with the actual test results and the traditional satellite simulation results to evaluate the significance of the virtual vibration test to the satellite development by analyzing the satellite frequency and the response magnitude.
