【摘要】 本文结合具体的WN齿轮实例,以齿轮的强度富裕最小作为优化设计目标,建立相应的强度优化数学模型,利用MATLAB优化工具箱的序列二次规划法(SQP)对其设计变量进行优化,进而分析该齿轮传动参数对接触和弯曲疲劳强度的影响。该优化方法不但实现了WN齿轮传动的优化设计,同时使设计出的齿轮装置具有重量轻、体积小等特点,提高了设计效率,为WN齿轮传动的CAD设计提供了科学的理论依据。更多还原

【Abstract】 This paper according with the example of WN gear,with the minimum gear strength as the optimization design goal and to establish the corresponding intensity optimization mathematical model.The research is to optimize the design variables by using the method of sequence quadratic programming(SQP) in MATLAB optimization toolbox.Analyzing the influence about gear drive parameters on contact and bending fatigue strength.This Optimization method not only achieved the optimization design of WN gears drive,but also makes the WN gear device has light weight and compact size.It improved design efficiency and provided theoretical basis for CAD design of WN gears drive.更多还原
