摘　　要：目前高空舱排气系统仿真计算领域存在几何建模耗时长、仿真流程慢等问题,为解决此类问题,本文根据高空舱排气系统的典型几何结构特点,采用参数化建模方案,通过对基础结构参数化模型的搭配组合形成满足计算要求的高空舱排气系统几何模型。通过对高空舱排气系统的几何模型进行计算网格的自动划分及数值计算,得到高空舱排气系统的流场及温度场分布数据,并与试验结果进行对比验证,结果表明:计算结果与试验结果的相对误差低于3%,满足工程实践要求。在此基础上,采用先进的计算机软件开发技术对上述分析流程进行封装及定制,并结合商业软件的二次开发技术,最终形成参数化的高空舱排气系统仿真软件集成封装平台。利用该平台可快速搭建参数化的高空舱排气系统模型,实现高空舱排气系统的全流程快速仿真。高空舱排气系统参数化计算平台具有高效、便捷、准确等优点。At present,there are some problems in the field of simulation calculation of the high altitude cabin exhaust system,e.g.geometric modeling is time-consuming and the process of simulation is slow.In order to solve these problems,based on the characteristics of the typical geometry structure of the high altitude cabin exhaust system,a parametric modeling scheme is adopted in this paper,and a geometric model of the high altitude cabin exhaust system is formed by combining the parameterized models of the foundation structure.Through automatic grid division and numerical calculation of the geometric model of the altitude cabin exhaust system,the flow field and temperature field distribution data of the altitude cabin exhaust system are obtained,and the data is verified by comparing with the test results.The results show that the relative error between the calculated results and the test results is less than 3%,which meets the requirements of engineering practice.On this basis,advanced computer software development technology is adopted to pack and customize the above analysis process,and combined with the secondary development technology of commercial software,a parameterized simulation software package platform for the high altitude cabin exhaust system is built.With this platform,a parameterized model of the high altitude cabin exhaust system can be built quickly,and the whole process of the exhaust system can be simulated quickly.The parameterized computing platform of high altitude cabin exhaust system presents the advantages of high efficiency,convenience,accuracy,etc.
