摘　　要：文章针对大型平板微波天线俯仰系统进行了工程研究。设计了一种强度高、重量轻的桁架结构做为天线背架，根据指标要求，建立数学模型，将整个运动过程通过准确的力学计算进行力矩分配，从而选定电机、减速机等结构要件，通过对关键结构件的有限元仿真及高功率微波的加固设计进一步保证整个俯仰系统良好的完成了实验，各项参数均能达到设计要求，微波测试方向图形态良好，波束指向满足要求。In this paper, the servo pitching system of a large plate microwave antenna is studied. The truss structure with high strength and light weight is designed as antenna back frame. According to the index requirements, the mathematical model process is allocated through accurate mechanical calculation to select the structure ele- ments such as motor and reducer. Through the finite element simulation of the key structure and the reinforce- ment design of high power microwave, the whole pitching system is further guaranteed to complete the experi- ment. All the parameters can meet the design requirements, and the direction pattern of the microwave test is good, and the beam direction meets the requirements.
