对矿用自卸车的刹车加力器存在的一些问题 ,采用有限元ViZiCAD软件对其强度和刚度进行了全面的分析研究 ,得出刹车加力器缸筒刚度不够 ,连接螺栓强度不够的结论 ,并提出了改进意见。
To some problems of brake booster of mining dump truck, the strength and stiffness of the brake booster cylinder are analyzed and studied by finite element method. The conclusion is that the stiffness of brake booster cylinder is not enough and the strength of connecting bolt is not enough. And put forward suggestions for improvement.
