摘要: 为了实现动车组转向架轻量化，设计了一种应用于动车组转向架的对扣式复合材料板簧和适用于重载的接头模块。对转向架复合材料板簧总成刚度进行了匹配设计，建立了对扣式复合材料板簧的刚度计算模型及铰接接头的可靠性理论模型。采用Abaqus软件建立板簧总成的有限元模型并通过CAE分析预测其刚度和强度，并对其可靠性进行分析，对试制的样件进行疲劳台架试验。研究结果表明，预测结果与试验结果的误差满足工程应用要求，且样件性能满足设计要求，证明了对扣式复合材料板簧的匹配设计和铰接结构可靠性理论的正确性，为动车组转向架复合材料板簧的应用提供了参考。
Abstract: To realize the lightweight of EMU bogies, a buckle-type composite leaf spring for EMU bogies and a joint module suitable for heavy loads were designed. The stiffness matching design of the composite leaf spring assembly for the bogie was carried out. The stiffness calculation model of the buckle-type composite leaf spring and the reliability theoretical model of the hinged joint were established. The finite element model of leaf spring assembly was established by Abaqus software and its stiffness and strength were predicted by CAE analysis, and its reliability was analyzed. The fatigue bench test of the trial sample was carried out. The results showed that the error between the predicted results and the experimental results met the requirements of engineering application, and the sample performance met the design requirements. The correctness of the matching design of the buck-le-type composite leaf spring and the reliability theory of the hinged structure were proved. These provided a reference for the application of composite leaf springs of EMU bogie.
