鉴于冲击压路机的滚动冲击压实轮和路面冲击对牵引主机平顺性的影响,对驾驶室悬置系统进行研究。在原有的被动减振系统基础上进行改进,建立基于磁流变阻尼器的半主动悬置模型。将传统的驾驶室被动橡胶减振系统与基于磁流变阻尼器的半主动控制悬置系统进行仿真对比分析,结果表明对磁流变阻尼器进行合理的控制,半主动悬置下驾驶室加速度及俯仰加速度较被动悬置有明显的降低,改善了主机驾驶室的舒适性。
In view of the influence of impact impact roller compacting wheel and pavement impact on the ride comfort of the traction engine, the cab suspension system is studied. Based on the original passive vibration damping system, the semi-active suspension model based on MR damper was established. The traditional cab passive rubber damping system and the MR damper based semi-active control suspension system are simulated and compared. The results show that the MR damper has a reasonable control, the semi-active suspension under the cab acceleration And pitch acceleration than the passive suspension significantly reduced to improve the comfort of the host cab.
