        摘要:本文以重卡钢板弹簧U形螺栓为研究对象,对其进行有限元建模和分析,并与试验数据对比,验证了有限元模型的准确性。在此基础上,通过有限元分析,探讨两U形螺栓距离和U形螺栓预紧力的大小变化,对钢板弹簧和U形螺栓内部应力的影响,为钢板弹簧和U形螺栓的设计提供了依据。

        Abstract: This paper sets up the analysis model of leaf spring and U-bolts on heavy truck. The analysis result was compared with the test result. Therefore the validity of the FEM model was proved. With the help of finite element method the relationship between the install distance of U-bolts and the stresses in leaf spring and in bolts was investigated. Furthermore the influence of assembly preload of U-bolts on the change of stresses in leaf springs and in U-bolts was analyzed as well. The results can provide reasonable reference for design of leaf springs and U-bolts.
