Research of Suspension System of Hydraulic Tramcar Based on AMESim

根据车辆行驶的评价指标,为提高矿车在凹凸不平路面行驶的平顺性,提出了液压悬挂系统,介绍了系统的结构、工作原理和液压系统原理图,并用AMESim仿真软件建立了仿真模型。仿真结果表明:液压悬挂系统可以有效地降低车身加速度、悬架动挠度和轮胎动位移,使车辆具有良好的行驶平顺性和操作稳定性。最后在多功能液压实验台上对伺服阀控液压缸的动态响应特性进行了实验,结果表明:所采用的液压悬挂系统能够满足矿车的使用要求。

A hydraulic suspension system was proposed according to the evaluation vehicle of improving the tramcar ride on uneven roads, and the system structure, working principle, hydraulic system schematic were described. Be-sides, the simulation model of the system was set up via the AMESim. The simulation indicates that this system can effectively reduce body acceleration, suspension deflections and tire displacement, so the vehicle has good riding comfort and operation stability. Finally, experiments of dynamic response of the servo valve controlled hydraulic cyl-inder were carried out on multi-function hydraulic bench. The results show that this system can meet the require-ments of the tramcar.
