摘　　要：橡胶垫在机车车辆一、二系悬挂系统上得到广泛应用,作用是绝缘、减振以及调整系统组合刚度,通过调整组合刚度能有效地改善机车车辆的动力学性能。文章首先从橡胶垫对一系悬挂装置系统组合刚度影响的角度出发,利用Abaqus软件建立了一系悬挂系统仿真模型,分析了不同结构的橡胶垫对系统组合刚度、橡胶垫应力和应变的影响;其次模拟橡胶垫实际运用工况,搭建了一系悬挂系统的刚度试验台,对装有不同结构橡胶垫的一系悬挂垂向刚度进行了试验测试,并与计算结果进行了对比分析,结合仿真计算和试验验证结果,最后选取对调整系统组合刚度最优方案的橡胶垫进行了产品开发。该橡胶垫顺利通过了疲劳试验,并装用于某出口动车组上,效果良好、性能稳定,为后续橡胶垫的开发提供了参考依据。Rubber pads are widely used in primary and secondary suspension systems of locomotive&rolling stock,and their functions are insulation,vibration damping,and adjustment of the combined stiffness of the system,which can effectively improve the dynamic performance of locomotive&rolling stock.From the perspective of the influence of rubber pads on the combined stiffness of primary suspension system,the article firstly establishes a primary suspension system simulation model using Abaqus software,and analyzes the influence of different structures of rubber pads on the combined stiffness of the system,rubber pad stress and strain;secondly,it simulates the actual use of rubber pads,and builds a primary suspension system stiffness test bench,and conducts tests on the vertical stiffness of primary suspension systems equipped with different rubber pads,and compares and analyzes the results with the calculation results.Combined with the simulation calculation and test verification results,the rubber pad with the optimal solution for adjusting the combined stiffness of the system was finally selected for product development.The rubber pad successfully passed the fatigue test and was installed in an export EMU with good effect and stable performance,which provides a reference basis for the development of rubber pad.
