【摘要】 振动压路机驾驶室的振动会影响驾驶员的操作舒适性,从多自由度振动解耦的角度出发,通过降低驾驶室多自由度间的振动耦合来提升驾驶室减振效果,并用Ada ms模型进行验证。结果表明:通过合理选择减振器刚度可以解除驾驶室沿竖直方向(Z轴)的平移自由度和绕左右方向(Y轴)的转动自由度间的振动耦合,显著降低驾驶室在前后方向(X轴)方向上的晃动;通过优化减振器水平安装位置和安装高度,可以进一步抑制振动耦合,提高驾驶室整体减振性能。更多还原

【Abstract】 As vibration in cab of the vibratory roller would affect operators’ comfort there has to reduce vibratory coupling among multiple degrees of freedom within the cab so as to upgrade vibratory reduction effects there,i.e.from the point of multi angle for vibration decoupling,which was followed by an Adams model for approval.The results showed that such vibration decoupling between translating freedom degree around Z axis and that around Y axis could obviously decrease sloshing forward and backward in X direction within the cab through logic selection of rigidity for the vibratory reducer.Nevertheless,through optimizing level fixing position and height of the vibratory reducer it can further suppress the vibratory coupling while increasing vibration reducing function of the cab as a whole.更多还原
