摘要:当前国内在发动机通用性能软件开发方面进展较为缓慢，与国外仍有较大差距。为了解决这一问题，提出了一种性能仿真软件的开发思路，并基于此完成了软件开发工作。基于C++语言，设计了一种面向对象的通用程序框架，可以实现多种仿真计算功能，包括稳态下的一维详细计算、容积法计算、实时计算以及瞬态计算。气缸、进排气道、管接头、涡轮增压器等主要组件包含多种计算模型，可以根据建模需求进行选择。针对某型中速柴油机，详细介绍了软件性能计算的操作流程，并将计算结果与试验数据进行对比。结果表明，软件有较高的计算精度，而且实时计算功能完全能满足实时分析的要求，实时率可以达到3.92。
Abstract:At present, the development of general engine performance software at home is relatively slow, and there is still a big gap with foreign countries. In order to solve this problem, a new development idea of engine performance simulation software was proposed, and the soft-ware was developed based on it. Using C++ language, a general program framework was established to realize various simulation calcula-tion functions, including one-dimensional detailed calculation, volumetric calculation, real-time calculation under steady state and transient calculation. The main components such as cylinder, intake and exhaust port, junction, turbocharger, etc., contained a variety of calculation models, which can be selected according to modeling requirements. For a medium-speed diesel engine, the operating process of perfor-mance calculation was introduced in detail, and the calculated results were compared with the test data. The results showed that the software has a high calculation precision, and the real-time calculation can fully meet the requirements of real-time analysis, and real-time factor can reach 3.92.
