摘　　要：为了减小限流阀对进气系统的影响,提高赛车发动机的动力性,以凯旋675自然吸气发动机为平台,开发了机械增压动力总成。通过机械结构、数据对比、仿真分析对机械增压器进行选型,确定了最佳的离心式机械增压器型号。利用GT-power软件建立了包括限流阀、机械增压器、中间冷却器、进气系统、排气系统、PID控制等模块的机械增压发动机一维仿真模型。拟合增压器效率MAP图,对发动机进行了性能仿真测试。结果表明,所选增压器与发动机匹配良好。研究结果可为大学生方程式赛车发动机及其他领域赛车发动机研发过程中机械增压器的选型、数据匹配、仿真分析提供一定的研究思路及分析方法。In order to reduce the influence of limit valve on intake system and improve the dynamic performance of racing engine,a supercharged powertrain was developed based on c-Triomphe 675 naturally aspirated engine.Through mechanical structure,data comparison and simulation analysis,the optimal centrifugal mechanical supercharger model is determined.A one-dimensional simulation model of supercharged engine was established by using GT-Power software,including limit valve,supercharger,intercooler,intake system,exhaust system,PID control and other modules.The engine performance was simulated by fitting the supercharger efficiency MAP.The results show that the selected supercharger matches the engine well.The research results can provide some research ideas and analysis methods for the selection,data matching and simulation analysis of mechanical supercharger in the development process of formula University racing engine and other racing engine.
