摘要
天线罩的几何加工精度是其优良电性能的前提保证。利用ANSYS软件研究天线罩内型面修磨加工过程中支架的变形和应力分布情况,应用ANSYS Workbench中的DesignXplorer模块对支架结构进行拓扑优化,并对优化前后支架的静态性能进行了分析比较。分析结果表明,优化后的支架重量得到减轻,刚度得到提高。利用此支架安装天线罩,减小了天线罩在加工过程中因支架变形而产生的误差,提高了天线罩的几何加工精度。
The geometric machining accuracy of missile radome is a guarantee of its excellent electrical properties. The stress and strain distribution of radome grinding installation support was studied with ANSYS. Using DesignXplorer module of ANSYS Workbench, proceeded topology optimization design for radome grinding installation support, and compared with static performance of the support before and after optimization. The analysis of the resuhs showed that the support after optimization saved weight, increased the rigidness. Carried by this support, radome reduced machining errors cased by support deformation, and increased the geometric machining accuracy.
