农用热气机热力性能计算的计算机模拟

Computer Simulation to Thermodynamic Performance of Farm Stirring Engine

运用Ｍａｒｔｉｎｉ的实用等温分析法，为热气机的整个热力性能计算建立了数学模型，编制了程序。该系统软件可计算任意工况下的有关性能参数。预测值与试验值对比分析表明，系统软件基本能满足设计计算要求。

By using the method of Martini isothermal analysis, the mathematic model was built on the specified construction form and the model was divided into six parts for programming. This system can be used to calculate the related performance parameters in any work condition. The main menu and Chinese man machine interface were developed. Therefore, the system is convenient to operate and easy to read. The comparative analysis between the predicted result and testing result was made. The result shows that they can meet the requirement for design.
