摘　　要：为实现汽车起步、加速、换挡的全工况仿真,提出了一种基于总成特性而用于驾驶模拟器的动力传动系模型。模型中离合器状态被分为分离、滑摩和接合3个相,而变速器则有空挡和非空挡两种状态,共组成了传动系运动学和力矩传递的6个组合相。为了离合器不同状态间的平稳过渡,建立了具有静动摩擦的离合器模型。起步换挡工况的仿真结果表明,所建动力传动系模型能较好地模拟汽车纵向加速性能,满足车辆动力学仿真要求。For carrying out starting, speeding up and shifting all condition simulation, a powertrain model neutral and non-neutral two states. So altogether six phase combinations of powertrain kinematics and torque transmission are composed. For the smooth transition of different clutch states, a clutch model with static and dynamic friction properties is built. The results of simulation verification on starting / train model built can better simulate the longitudinal acceleration performance quirements of vehicle dynamics. shifting condition show that the power- of vehicle, meeting the simulation requirements of vehicle dynamics.
