摘　　要：矿用汽车货厢与车架在车架尾部通过销轴联接,在实际使用中,发现该处销轴磨损严重。建立了包括横向稳定杆在内的矿用汽车半车振动模型,分析出导致该销轴磨损严重的主要原因在于矿用汽车的横向振动。且分析结果表明:汽车的载货质量越少,行驶速度越大,横向稳定杆与水平面的初始夹角越大,横向稳定杆有效长度越长,后桥对车架的位移激励越大,则联接车架与货厢的销轴越易磨损。最后通过实车试验验证了货厢与车架在销轴处确实存在相对滑动。Mine truck＇s carriage and frame are connected by the pin in the rear of frame. In actual use, there exists＂ a serious pin abrasion. This paper builds the mine truck＇s semi-truck vibration model including the lateral stabilizer bar and analyzes that the major cause of the serious pin abrasion lies on the lateral vibration of the mine truck. Moreover, the results show that, the less the mass of the mine truck loads＇, the quicker the speed is, the larger the initial angle between the lateral stabilizer bar and the horizontal plane, the longer the effective length of the lateral stabilizer bar, the greater the displacement excitation of the rear axle relative to frame, so the pin connecting frame and carriage is easier to wear. Finally, it＇s certificated by the real vehicle test that there exists the relative sliding in the position of connecting pin between carriage and frame.
