Equipped With Dual-mass Flywheel Hybrid Powertrain Design And Matching

Hybrid vehicles as the main development direction for the future of the automobile, the hybrid vehicle power matching the importance of research is becoming increasingly clear that the key technology is the design and selection of multi-power coupler. Two different forms of power for the engine and motor match, matching dual-mass flywheel-based multi-dynamic coupling with the hybrid drive train is the focus of this study.This article is equipped with dual-mass flywheel hybrid vehicle drive system as the object of study around the transmission system in the following areas:1. Form of multi-power hybrid vehicles; hybrid vehicles, the kinetic parameters of the match; double mass flywheel torque coupler key technologies; vehicle model-based optimization and validation.Firstly, based on a variety of models of hybrid vehicles, analysis of the domestic and international development and Research presented the Hybrid Electric Vehicle diversity, combined with the existing multi-dynamic coupling. The basic components of the dual mass flywheel as a multi-power coupler, the matching of the hybrid power train. As the content of this article.Secondly, the relationship between the driving force in the form of hybrid vehicles, the research engine torsional vibration and the engine speed, power, harmonic mechanical model; synchronous motor instability, disturbances in the external moment of motor power output and input; and the establishment of the association model of the vehicle road conditions, road spectrum with the vehicle transmission.Thirdly, with reference to existing mainstream models, parametric settings, based on the Advisor, completed the construction of virtual models, including the ideal working speed range of the engine, synchronous motors and generators, torque and power.Fourthly, as a core component of the multi-dynamic coupling is derived to calculate the long curved spring design theory, combined with the test of the static stiffness and dynamic torsional vibration damping test, pushed to the mechanical dynamic model of the dual-mass flywheel; and based on two degree of freedom model to match the dual-mass flywheel to the vehicle to study the efficiency of the transfer of dual-mass flywheel and build a dual-mass flywheel power coupler operating principle model.Finally, the use of Matlab/Simulink module, the establishment of a hybrid car vehicle model, the analysis based on specific operating conditions of automotive driveline dynamic performance, and to match the dual-mass flywheel coupling for parametric design and matching study.
