摘　　要：针对采用拉维娜行星齿轮机构和传统多挡变速器的并联混合动力构型选择,采用基于杠杆法以挡位设计规则、动力特性规则、工作模式规则、可制造性规则相结合的一种综合评价方法,对混合动力系统构型进行分析和筛选,并确定了构型方案和该方法的筛选流程。其次针对整车的设计目标,对发动机、电机的参数进行了选择,并运用GT-SUITE软件搭建整车纵向动力学模型。在此基础上,采用Pareto前沿对变速器参数进行了优选,最终在确定混合动力构型的基础上,优选确定了混合动力系统的设计参数,并通过仿真验证了方案的可行性,为采用拉维娜行星齿轮机构和传统多挡变速器的并联混合动力系统研究提供了理论依据。This paper focuses on the screening of parallel hybrid power system configurations employing the Ravigneaux planetary gear mechanism and traditional multi-gear transmission.A comprehensive evaluation method,integrating gear design rules,dynamic characteristics rules,working mode rules,and manufacturability rules based on the lever method,is applied to analyze and screen the hybrid power system configurations.The configuration scheme and screening process of this method are determined.Subsequently,in line with the vehicle′s design objectives,parameters of the engine and motor are selected.The vehicle′s longitudinal dynamics model is established using GT-SUITE software.On this basis,transmission parameters are optimized using the Pareto frontier method.Finally,upon determining the hybrid configuration,the design parameters of the hybrid power system are optimized and determined.The feasibility of the scheme is validated through simulation,providing a theoretical basis for the research of parallel hybrid power systems using the Ravigneaux planetary gear mechanism and traditional multi-gear transmission.
