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。
Vibratory roller cab vibration will affect the driver’s comfort of operation, from a multi-degree of freedom vibration decoupling point of view, by reducing cab vibration coupling between degrees of freedom to enhance cab damping effect, and Ada ms model verification. The results show that the vibration coupling between the cab along the vertical direction (Z axis) and the rotational freedom around the Y axis can be released by reasonably selecting the stiffness of the shock absorber. This can significantly reduce the cab longitudinal displacement (X-axis); By optimizing the horizontal mounting position and installation height of the shock absorber, vibration coupling can be further suppressed to improve the overall vibration damping performance of the cab.
