摘要

为提高四轮独立驱动系统的驱动力应用效率,提高特种车辆的控制能力、动力性和稳定性,开展了四轮驱动力分配模式的研究。根据实体车辆结构搭建了四轮独立驱动平台物理模型,基于ADAMS软件搭建了虚拟样机模型;通过3种驱动力分配模式下车辆在平直路面匀速行驶状态下的动力学仿真,分析了等转矩和等状态两种驱动力分配模式下的车辆运行状态;以及在车轮不同转矩模式下车辆运动情况。仿真结果表明,驱动转矩的分配比例与质心位置有关,等状态模式在车辆正常行驶情况下性能较好;当左右车辆驱动转矩不同时,车辆跑偏程度主要取决于左右两侧驱动力的差值。

Abstract

In order to improve the efficiency of driving force and the control ability of special vehicle,dynamic performance and stability,the distribution pattern of the four-wheel independent drive system is studied. A platform physical model with four-wheel independent drive is set up according to the real vehicle structure,and the virtual prototype model is built based on the ADAMS software. Through dynamics simulation under three driving force distribution modes of vehicle on straight road vehicle condition,the influence of vehicles running state is analyzed with equal torque and equal state driving force distribution model,and the influence factors of vehicle running deviation is studied with different wheel torque mode. The simulation results show that the drive torque optimal allocation proportion is associated with the location of the center of mass and equal state pattern is better. When the vehicle driving torque is not equal,vehicle running deviation degree mainly depends on the difference between left and right sides of the driving force.
