摘　　要：为解决某重型车辆驾驶室抖动问题,通过制动抖动整车道路再现试验研究,分析了抖动现象的特征,确定了制动力作用下驾驶室抖动振动的传递路径,得出车架悬架系统X、Y方向限位刚度不足是导致驾驶室抖动的主要原因。在上述分析的基础上对车辆抖动问题提出了解决方案,并对原车进行了试验验证,结果表明所提出的解决方案很好地解决了驾驶室制动抖动问题,同时验证了分析的合理性和可行性。In order to solve the cab jitter problem for a heavy-duty truck,an experimental research on the cab jitter phenomenon induced by brake judder was carried out.The characteristics of cab jitter and the effect factors were analyzed.The vibration transfer path of cab jitter under braking force was clarified,which indicates that the insufficient stiffness of suspension system in X and Y directions is the main reason to lead to cab jitter.On the basis of the test analysis,a solution for cab jitter was put forward,and the vibration reappearance test for cab jitter was performed in a road test.The results show that the proposed method can solve the problem of brake cab jitter and validates the rationality and feasibility of the test analysis.
