摘　　要：采用ABAQUS软件建立H5G型号后驱动桥的钢板弹簧有限元模型;在相邻簧片之间施加接触单元,模拟簧片之间的法向与切向接触特性;簧片中心螺栓孔内建立分布约束,并把不同簧片螺栓孔内的耦合点刚性连接模拟螺栓联接;在两端卷耳中心与卷耳内表面建立MPC多点耦合,约束钢板弹簧一端参考点123方向自由度,约束另一端参考点13方向自由度模拟板簧与板簧支架之间的联接。计算结果表明:板簧装配体整体变形最大应力为888MPa,满足强度要求,接触力与模态分析钢板弹簧的簧片接触机理及震动特性提供理论参考。Using ABAQUS software to build models of leaf spring rear axle is H5G finite element model, including： applying a contact unit between adjacent reed, reed contact characteristics between the analog; reed build distribution center bolt hole free to establish a reference point at the center of both ends of the word, the direction of the leaf spring end 123 bound reference point freedom constraint reference point 13 and the other end direction; constraints, and the point of cou- pling bolt holes of different spring bolt preload rigidly connected to an analog connection the degree of coupling between the analog plate spring and the body.The results show that： the leaf spring assembly, overall deformation maximum stress is888 MPa, meet the strength requirements, the contact force and modal analysis of the leaf spring and vibration characteristics of the reed contact mechanism provides a theoretical reference.
