【摘要】 齿轮轴是齿轮油泵核心零件之一,为研究其结构的优劣对齿轮油泵使用寿命的影响。首先利用Solidworks软件建立齿轮油泵三维实体模型;然后在定义设计疲劳曲线(S-N曲线),利用Solidworks Simulation插件对齿轮轴进行疲劳分析,最终得出齿轮轴的对等应力等相关数据,进行有限元分析。研究结果表明,该研究为预测齿轮油泵的疲劳寿命提供了理论依据。更多还原

【Abstract】 Gear shaft is one of the core parts of gear pump,In order to study the influence of structure on the service life of gear pump. Firstly,the gear oil pump 3D solid model by using Solidworks software; then in the definition of design fatigue curve( S-N curve) on the basis of gear shaft,the fatigue analysis of the gear shaft with Solidworks Simulation,drawgear shaft equivalent stress and other related data,finite element analysis.The results showthat,the study provides a theoretical basis for the prediction of the fatigue life of the gear oil pump.更多还原
