摘　　要：柔性负重轮系能够使可更换履带轮的接地部分顺应地形变化,而刚性负重轮系不具备这一特性.为研究柔性负重轮系对可更换履带轮的性能影响,使用ADAMS仿真对比2类负重轮系在水平路面和障碍路面上行驶状况.其中,在水平地面上评估由履带链节模拟橡胶履带引起的多边形效应.仿真结果表明,多边形效应不造成2类负重轮系在振动和行驶速度上的差异,但柔性负重轮系与刚性负重轮系相比,能够降低履带轮行驶时的振动,提高其牵引性能并利于越障.The flexible roller wheel system enables conversion track assembly to conform to terrain fluctuation while the rigid roller wheel system does not have this characteristic.To study the influence of the flexible roller wheel system on the performance of conversion track assembly,a multi-body dynamic simulation method is proposed to compare the efficiency of vibration reducing and obstacle crossing of the flexible roller wheel system and that of rigid roller wheel system.In simulation,polygon effect is estimated by travelling simulation on horizontal ground,which is caused by using track links to model rubber track approximately in ADAMS.Simulation results demonstrate that polygon effect does not make difference between the two roller wheel systems,and the flexible roller wheel system can obviously reduce vibration caused by obstacles,facilitate the track assembly climbing obstacles and improve its tractive performance.
