高超声速飞行器天线罩热-电联合仿真计算方法

摘要

探讨基于ANSYS Multiphysics和FEKO商业软件平台,对天线罩进行热-电联合仿真计算的实现途径和基本步骤.利用传统的烧蚀计算程序和ANSYS Multiphysics仿真模块对某型号天线罩进行烧蚀、温度场计算,采用温度控制方法将天线罩分层,从而将天线罩烧蚀和高温状态下的电性能仿真问题转化为常温状态下的多层介质的电性能仿真问题,在FEKO软件平台进行求解,并在此基础上探讨建设天线罩热-电联合设计平台的可行性.%Based on ANSYS Multiphysics and FEKO, the approach and process on simulation calculation of thermo-electricity is given. Utilizing the traditional ablation calculation program and ANSYS Multiphysics simulation module, the temperature and ablation of a warhead radome is calculated. The radome is delaminated by temperature control method, so that the simulation calculation of thermo-electricity about the radome in high temperature and ablation could be translated into the one about multilayer medium radome. Based on FEKO software, the problem can be resolved, and the feasibility on building the platform of thermo-electricity design is discussed.
