摘　　要：以装用转8A型转向架的罐车为分析对象,介绍了影响三大件式转向架抗菱刚度的因素,结合动力学计算模型,分析计算了抗菱刚度数值对该转向架车辆蛇行运动规律和安全运行的影响趋势,为保证现有货车的安全运行提出了检修建议。The tank car with Zhuan 8A bogie is regarded as the analysis object. The factors affecting the diamond resistant rigidity of the three-pieced bogies are described. With the combination of the dynamics calculation model, the trend of effect of the diamond resistant rigidity value on the hunting motion pattern and safety operation of the car with the bogie is analyzed and calculated, in order to ensure the existing safety operation of freight cars, the suggestions for inspection and repair are given.
