摘　　要：根据多波束天线的跟踪运动形式，在二面倾斜、大负载、重心偏置的困难条件下设计副面调整升降机构，结合ANYSY软件对升降机构整机进行有限元分析，使其满足强度、刚度等综合性要求，并能圆满地完成工作。According to the tracking motion form of the multi-beam antenna, the adjustment and lifting mechanism of the sub-reflecting surface is designed under the difficult conditions of two-sided tilt, large loaded and center offset. The finite element analysis of the lifting mechanism is carried out in combination with ansys software to satisfy comprehensive requirements such as strength and rigidity.
