Research On Analysis, Optimal Matching Of Automobile Power-train And Application Software Development

Firstly, this paper discusses research actuality of analog calculation and matching of automobile power-train. Synthetical evaluation index system of tractive performance and economic performance of automobile is presented on the base of summarizing former studies. On the base of building mathematical models of tractive performance and economic performance, synthetical optimization model of transmission parameters is presented;And building mathematical models of flexibility coefficient of correlative parameters affecting tractive performance and economic performance.Secondly, based on the building model of parameters optimization and analysis of automobile power-train, and combine each excellence of MATLAB and Visual C++ program language, develop a set software of parameter analysis and optimization of automobile power-train for personal computer. With this software, parameters flexibility coefficient analysis and optimization of power-train are done to some type bus of An-Kai company.Finally, according to similarity engineering theory, building the model of similarity calculation of automobile power-train, from the similarity of power-train structure and vehicle performance to discuss the application of similarity engineering theory in matching of power-train.
