轮轨接触应力的有限元分析
The FEM Analysis of the Wheel-rail Contact Stress
【摘要】 利用ANSYS有限元分析软件对轮轨接触进行了弹性静力分析,模拟了轮轨真实的几何形状和边界条件,分别研究了轴重、轮径、横移量对接触应力的影响,并对各种参数的变化规律进行了分析,得出了轮轨间接触应力的分布规律。
【Abstract】 ANSYS FEM is used to solve the elastic and static wheel-rail contact problem.The real geometry and edge conditions of wheel-rail are simulated and the influence of different wheel diameters,different axle loads and different lateral shift of wheel set on contact stress are studied.The paper shows that the most important factor is the lateral shift.
