摘　　要：为了快速设计及分析车轮的疲劳强度,基于VC++与APDL对车轮进行参数化设计,建立了友好的参数化设计界面;利用VC++与MATLAB混合编程法编制了专业的车轮疲劳后处理软件,程序的移植性好,可脱离MATLAB环境运行。根据UIC510-5标准对车轮进行了强度分析,利用4种多轴疲劳评定方法对车轮疲劳强度进行评定。比较研究表明,各种多轴疲劳方法评定的车轮辐板区域的安全系数分布趋势基本一致,最小安全系数存在一定差异,在车轮的疲劳强度评定中,认为UIC法应为最优选择。In order to quickly design and analyze the fatigue strength of the wheel, parametric design of the wheel was designed based on VC＋＋ and APDL. Professional wheel fatigue post-processing software was compiled by using of the hybrid programming of VC ＋ ＋ and MATLAB. The program could be transplanted between different computers without MATLAB software. The strength of worn wheel was analyzed in terms of UIC510-5 standard. The fatigue strength of worn wheel was analyzed by using four multi-axial fatigue evaluation methods. The results showed： the distribute trend of the wheel＇s safety factor was almost the same, but the minimum safety factor of different methods was different. The UIC method should be the optimal choice in the wheel fatigue strength assessment.
