摘要
螺旋锥齿轮齿面复杂,为了研究机床几何误差对齿面偏差的敏感性,在建立螺旋锥齿轮齿面加工偏差模型的基础上,分别采用局部敏感性分析方法和Sobol全局敏感性分析方法,研究输入参数范围变化对输出结果的影响,确定了影响齿面偏差的关键几何误差。从输入参数和输出结果两个方面比较了两种分析方法的特点。明确了敏感性分析方法的选取原则:对于输入参数的分布范围不明确或者分布情况相似的线性或非线性不强的模型,可以考虑采用局部敏感性分析;对于输入参数的分布范围复杂、准确性要求高的非线性模型,适于采用全局敏感性分析方法。
The tooth surface of spiral bevel gear is complex.In order to study the sensitivity of machine tool geometric error to tooth surface deviation,based on the establishment of spiral bevel gear tooth surface machining deviation model,the local sensitivity analysis method and Sobol global sensitivity analysis method were used respectively,to study the influence of input parameter range change on the output result.The key geometric error affecting tooth surface deviation was determined.The characteristics of the two analysis methods were compared from two aspects of input parameters and output results.The selection principle of sensitivity analysis method was defined:for the model which distribution range of input parameters is not clear,or the linear or nonlinear distribution is similar,local sensitivity analysis can be considered;for nonlinear models with complex distribution of input parameters and high accu-racy requirements,global sensitivity analysis method is suitable.
