Development On Numerical Simulation Software About Air-conditioning Effect In High-speed Train

At present, using the CFD technology for numerical simulation analysis of train is more and more important, and absolutely necessary,but the process need to enterprise cost a lot of energy,modeling and calculation process both very complicated,and for the professional requirements of users is very high,so it’s difficult to enterprise the CFD technology used to train research and development and production process.so Enterprises urgently need to develop a simple and easy software platform to operate, to reduce the threshold for the users,quickly and easily, to improve the efficiency of design research and development,So, the development of numerical simulation platform is very vital significance.The content of the research is the fluid software secondary development, namely to develop a software platform, the software oriented to train production enterprise engineers or engineering technical personnels,software platform can achieve such a purpose:rapid parameterized automatical ly,automatic numerical simulation calculation,post-processing results intuitive display,the results validate and evaluate solutions.Developed by secondary programming language Visual Basic to design platform system,involved in modeling software GAMBIT and fluid calculation software FLUENT of secondary development,mainly for its JOU scripting language to write command statements,and then by VB to connect,interface design and coding.The design software platform has43interfaces,163JOU files,tens of thousands of bar codes,Three models of the emu CRH5,CRH3,CRH7parametric modeling and simulation calculation, and then evaluation about its solution.The project of the secondary development of software products is the enterprise’s right-hand tool,research into the railway passenger in our country about air dynamics has application value,meanwhile,to research and development of the other industries products has extensive demonstration roles.
