摘要
利用ANSYS软件 ,对机车轮对进行了应力、变形的非线性分析 ,并对轮箍加装扣环前后其配合面内的接触应力分布进行比较 ;详细讨论了直线持续牵引工况中 ,轴重、牵引力、水平侧向力等对机车轮对应力分布的影响 ,模拟分析了在加载作用下 ,加装扣环前后轮对配合面的应力分布情况。通过分析计算 ,确定了机车轮对轮箍加装扣环方案对轮对的强度的影响。
The non-linear analysis about the stress and the deformation of the train wheel are analysed by ANSYS software. For the tyres are equipped with buckle or without, the distributive contact stresses are compared on two fit surfaces. During the situation of linear successive traction, influences of the distributive contact stresses by shaft-weight, tractive-stress and horizontal side-stress, are discussed in details. Finally, the influences are also compared after loading. Through analysis and counting, strength impact about the schema of the wheel equipped with buckle is confirmed.
