摘要
对多模块铰接式车体的曲线通过进行了仿真分析与试验.分析了多模块铰接式车辆的架构和主要技术参数,利用MSC ADAMS多体系统动力学软件分析车辆在15 m最小平曲线半径、S型曲线及最小缓和曲线半径(R=200 m)爬坡(坡度13%)工况下结构运动自由度及结构部件之间的干涉情况,并计算铰接位置的相对运动转角;利用1:1的模型车进行曲线通过验证,确认车体满足车辆运行需求.将仿真分析与试验结果对比,确认仿真计算与试验情况相符.
Experiment resultsare described,and dynamical simulations are studied on the small radius curved-track negotiations onto multi-body articulated car body of the guided rubber-typed tram.A finite element analysis based on MSC ADAMS is focused on the introduction of the DOF(dimension of freedom),and the interference of the mechanism is checked on minimum radius(R=15m),S type curve and transition curve radius(R=200m)and climbing steep(i=13%),etc.Measurement of the relatively rotation displacement between the carbody and main structure is conducted,and the reasonableness of the multi-body articulated car body system modelis verified through test.Good agreement is obtained between the numerical and experiment results,and the operating relationship meets the vehicle operational requirements.
