分析了智能振动压路机多模式调整原理;并根据其结构特点,提出一种基于水平振荡和垂直振动的整体动力学模型.以XG6133D型智能压路机为例,研究了压实进程中振动轮、机架在多模式下及减振系统参数发生变化时的动力学响应特性.仿真结果表明,在压实进程中应主动控制减振器参数和调整激振模式,以提高压实效率及改善驾驶舒适性. Multi-mode adjustable principle of intelligent roller was analyzed.An new dynamic model based on vertical vibratory and horizontal oscillation was proposed according to the structural feature of intelligent roller.Taking the XG6133D intelligent roller as an example,the dynamic characteristics of drums and framework in the compaction process of different vibration modes was investigated.The simulation results demonstrated the shock absorber parameters were actively controlled and the vibration mode was adjusted in the compaction process to enhance compaction efficiency and driving comfort.
