摘　　要：以标准齿轮接触试验台的基本参数为非标齿轮样件设计依据,考虑到齿轮啮合、加工及胶合等因素,建立以电机耗能最低、实验齿轮疲劳寿命最短,且陪试齿轮疲劳寿命最长,为目标函数的优化模型。运用改进后的非支配排序遗传算法,引入了精英策略和快速非支配排序法来提高计算结果的精度和运算效率,在标准试验台上,探讨和挖掘非标因素对齿轮承载能力影响的齿轮样件设计方法。本文中以两种不同中心距的试验台为实例,验证用标准试验机来研究非标齿轮设计方法的正确性。结果表明:用标准齿轮接触试验台来研究非标准齿轮接触疲劳寿命的方法具有有效性。Based on the parameters of standard gear contact test bench, a non-standard gear specimen was designed in this paper. Considering the gear meshing, processing and gluing, a multiple objective function optimization model was established, which aimed to the minimum energy consumption, the shortest fatigue life of test gear and the longest fatigue life of accompany trial gear. In order to improve the accuracy of computation and operation efficiency, Non-dominated Sorting Genetic Algorithm-ll was used and the elitist strategy was introduced. Considering the non-standard factor influ- ence on carrying capacity of gear, gear specimen design procedure was discussed and developed. Taking the two test benches of different center distances in Jinan Shijin group and Newcastle University for examples, the design procedures correctness was verified, in which the non-standard gear can be researched on standard testing machine. It was conclu- ded that usin~ standard ~ear contact test machine to study non-standard ~ear contact fatigue life is effective.
