基于NSGA-Ⅱ的弧齿锥齿轮参数化建模与多目标优化设计
Parametric Modeling and Multi-Objective Optimization of Spiral Bevel Gears Based on NSGA-Ⅱ Algorithm
摘要
Abstract
Aimed at the current problems of large transmission error,high contact temperature and high contact Hertzian stress of the spiral bevel gears,an optimization method based on optimal parametric modeling and non-dominated sorting genetic algorithm was proposed.Firstly,based on Kiss soft software,the spiral bevel gears were parametrically modeled to clearly describe their parameter variation characterist-ics.Secondly,the spiral angle,pressure angle and tooth width were taken as the optimization variables,and the transmission error and longitudinal overlap were taken as the objective functions,and the multi-object-ive parameter optimization design was performed for the spiral bevel gears based on the second-generation non-dominated sorting genetic algorithm(NSGA-Ⅱ).Simulation results show that the longitudinal overlap of the optimized gear pair is increased to 21.92%,while the transmission error,contact temperature,and contact Hertzian stress are reduced by 46.90%,23.69%,and 32.19%,respectively.The proposed optimized design significantly improves the smoothness of the gear pair transmission,increases the gear life,load car-rying capacity,transmission efficiency and reliability,and effectively reduces the vibration and noise of the gears.关键词
