摘要
为了解决井下无轨胶轮车转向系统转向沉重、稳定性差、能耗高等问题,引入线控主动转向系统,基于Car Sim软件建立线控转向整车动力学模型,采用横摆角速度反馈控制方案,在Simulink软件中搭建控制框图。对线控主动转向系统分别进行对开路面和双移线仿真分析,并与传统转向系统进行对比分析,结果表明,线控主动转向系统可显著改善无轨胶轮车的转向特性。
In order to solve the problems of steering heavy, poor stability and high energy consumption of the steering system of underground trackless rubber-tyred vehicle, the wire control active steering system is introduced. Based on the CarSim software, the vehicle dynamic model with wire control active steering system is established. The feedback scheme of horizontal pendulum angular velocity is used to construct control block diagram based on Simulink software. The wire control active steering system is simulated by splitter road and double lines experiment, and the simulation results of the wire control ac- tive steering system and traditional steering system are contrastive analyzed. The analysis results show that the wire control active steering system is good to improve steering characteristics of underground trackless rubber-tyred vehicle.
