中文摘要：
为了分析铁路货车车轮的疲劳强度，建立了车轮轴对称模型，根据国际铁路联盟标准UIC510一5／2003规定的计算载荷和载荷工况，计算了车轮的疲劳强度，用Goodman曲线对疲劳强度进行了评定。计算结果表明：在紧急制动的热载荷作用下，车轮辐板区域在制动70S时产生最大von—Mises应力；在紧急制动的热载荷与机械载荷联合作用下，车轮辐板区域在制动43S时产生最大von—Mises应力；在曲线紧急制动载荷工况的计算载荷作用下，车轮辐板区域的von—Mises应力最大；车轮辐板疲劳强度满足要求。
英文摘要：
In order to analyze the fatigue strength of wheel for railway freight car, an axisymmetric model was set up, the strength was computed according to the calculation load and load conditions of international railway union standards UIC510-5/2003, and the strength was assessed by using Goodman curve. Calculation result shows the maximum von_ Mises stress appears on the spoke under the thermal load of emergency braking when the braking time is 70 s, the maximum von_Mises stress appears on the spoke under the thermal load and the mechanical load of emergency braking when the braking time is 43 s, the maximum von Mises stress appears on the spoke under the calculation load of curvilinear emergency braking, and the fatigue strength of the spoke meets the relative requirement. 7 figs, 12 refs.
