摘要：

为了匹配设计某轻型客车复合材料板簧的刚度,设计复合材料板簧的总成结构,通过试验获取E玻纤/聚氨酯层合板的力学性能参数.根据板簧设计理论及经典层合板理论,采用MATLAB软件编写复合材料板簧的刚度计算程序.通过该计算程序计算了铺层关键参数与复合材料板簧刚度之间的关系.以MATLAB刚度计算程序及铺层关键参数与复合材料板簧刚度之间的关系为基础,建立复合材料板簧刚度匹配设计的完整计算程序,并设计复合材料板簧的铺层方案.在ABAQUS软件中建立了复合材料板簧的有限元模型,通过有限元模拟来验证设计的复合材料板簧的刚度.对设计的复合材料板簧进行台架试验.试验结果表明,复合材料板簧刚度的预测值与试验值接近,说明提出的刚度匹配设计方法正确、有效,这对复合材料板簧的推广应用具有重要意义.
Abstract:

The structure of the composite leaf spring was designed in order to match design the stiffness of a composite leaf spring used in a light bus, and the mechanical properties of glass fiber reinforced polyurethane laminate were tested. The MATLAB program, which can calculate the stiffness of composite leaf spring by using certain layer scheme, was written by MATLAB software according to the leaf spring design theory and the classic laminate theory. Then the relationship between the key parameters of layer scheme and the stiffness of composite leaf spring was calculated by using the MATLAB program. Finally,the layer scheme of the composite leaf spring was designed according to the complete computer program,which was established on the basis of the MATLAB program and the relationship between key parameters of layer scheme and the stiffness of composite leaf spring. The finite element model of the composite leaf spring was established using ABAQUS software and the stiffness of the composite leaf spring was verified by using finite element method. The bench test for the composite leaf spring was carried out. The test results demonstrate that the predicted stiffness is close to the test stiffness, so the designed method,which is significant in the promotion and application of composite leaf spring,is correct and valid．
