摘　　要： 研究计量泵箱体受力规律,分析箱体结构对计量泵使用寿命的影响,优化箱体结构尺寸,提高箱体的生命周期。以流体力学为基础计算计量泵在实际工况中箱体最大作用力;使用Solid Works Simulation软件对箱体进行静力学分析;以箱体静力学分析及材料S-N曲线为基础,对箱体进行疲劳分析;根据分析结果对箱体尺寸数据进行优化。从各项分析结果可以看出,箱体最大受力为11630N,箱体内部加强筋处最大应力为85.13MPa,经过优化箱体寿命提高625.5倍。 This paper studies the force law of the metering pump box,analyzes the influence of the box structure on the service life of the metering pump,optimizes the size of the box body,and improves the life cycle of the box body. On the based of Hydromechanics to calculate the naximum force of metering pump in actual conditions; makes the static analysis of the box body by SolidWorks Simulation software; base; on the static analysis and the material S-N curve to do the fatigue analysis of box body; according to the results of the analysis to optimize the box size data. It can be seen from the analysis results that the maximum stress of the box is 11630N,the maximum stress of the reinforcement inside the box is 85.13MPa,and the service life of the box is increased by 625.5 times by optimizing.
