基于NSGA-Ⅱ与欧氏距离法的齿轮多目标综合修形设计
Multi-objective comprehensive modification design of gears based on NSGA-Ⅱ and Euclidean distance method
摘要
Abstract
The high torque and high-speed characteristics of new energy vehicle drive motors exacerbate vibra-tion,noise,and temperature rise in gear transmission systems.Tooth profile modification is an effective solution to these problems.However,existing modification designs primarily focus on improving a single performance aspect,lacking consideration for comprehensive multi-performance enhancement.To address this,a comprehensive cross-physics-field tooth profile modification design method for gears was proposed,combining the non-dominated sorting genetic algorithm Ⅱ with the Euclidean distance method.A mapping relationship was established between tooth profile modification parameters and cross-physics-field multi-performance indicators,such as load distribution coefficient,dynamic transmission error,and tooth surface flash temperature.Taking the maximum modification amount and modification index as design variables,with the goal of achieving optimal system multi-performance,a cross-physics-field multi-objective comprehensive modification optimization model was developed.The non-dominated sorting genetic algorithm Ⅱ was employed to obtain the Pareto solution set of design variables,and the Euclidean distance method was used to select the optimal modification parameters for comprehensive multi-objective performance.The results demonstrate that under the comprehensively optimal modification param-eters,the abrupt change value of the load distribution coefficient at key nodes on the meshing line decreased by 87%,the fluctuation range of dynamic transmission error was reduced by 85.6%,and the peak tooth surface flash temperature dropped by 27.8%,achieving comprehensive system performance improvement.The multi-objective comprehensive performance reached 93.3%of the optimal performance for each single objective.This study over-comes the limitations of single-objective modification and provides an effective cross-physics-field comprehensive modification design method for optimizing gear transmis-sion systems.关键词
