Abstract

Aim at dual-mode hybrid drive system complexity electromechanical coupling problems, the thesis reveals system electromechanical coupling law from two levels, power coupling and vibration coupling, establishes a hybrid drive system power flow distribution model, and studies the law that the power flow distribution ratio with the speed and power battery charge and discharge power ratio changes. In order to further study the hybrid drive system coupled vibration law, establish incentive model of the engine torque model nonlinear harmonic meshing force of permanent magnet synchronous motor and gear incentive model. In the case of multi-source excitation, the vibration study conducted multi-stage planetary transmission at different power flow distribution ratio obtained with dynamic load variation coefficients are set coefficients and energy evaluation index system for the various parameters, for the hybrid drive system control strategy and system design to provide a theoretical reference.
