为准确预测联合收割机行走半轴的失效部位以及使用寿命，利用nSoft 软件的数据处理模块合成了联合收割机行走半轴典型工况的载荷谱；采用SolidWorks 软件建立了联合收割机行走半轴的三维有限元模型，并用载荷谱外推后的最大值进行加载，得到行走半轴花键处的剪切应力云图和等效应力云图，等效应力的最大值小于材料的屈服极限；基于Simulation 模块中定义的 S-N 曲线对行走半轴进行了疲劳分析，预测了行走半轴花键齿根部的工作寿命为2752h，与厂家提供的售后使用记录中的行走半轴失效时间较为接近。

In order to predict the failure location and service life of half axle of combine harvester precisely , the load spectra of half axle in typical working conditions was compiled by using the software of nSoft , the three-dimensional finite element model of half axle was established by using SolidWorks and the external load was added on the basis of the load spectra , the stress contour plot of half axle showed the maximum Von Mises stress was less than yield limit , the fatigue life contour plot of half axle was created based on the S-N curve defined in the Simulation module , it predicted that the working life of the spline root was 2752 hours about , the result is close to the actual failure time of the half axle .
