摘　　要：高机动雷达平台承载天线座及天线阵面等关键设备,其刚强度优化设计至关重要,直接影响雷达的使用安全性和测量精度。文中对某雷达平台骨架进行了优化设计,采用有限元分析手段对骨架结构进行了仿真分析,考察了应力及变形指标,针对局部应力集中提出了优化改进措施。采用应力测试方法对骨架的应力进行了测试评估,结果与有限元分析相符。The platform framework of highly mobile radar supports key equipment such as antenna pedestal and antenna array,its stiffness and strength optimization is very important and directly influences the use safety and measuring accuracy of radar. In this paper,optimization design for the platform framework of a highly mobile radar is carried out. Finite element method is used for simulation analysis of framework structure. The stress and deformation are evaluated,and optimizations are proposed for partial stress concentration. Then a stress test platform is applied to test the actual stress of the physical platform framework,the results agree with simulation.
