【摘要】：依据前期研究的四行星齿轮泵的流量脉动特性为基础,建立了相应的压力脉动数学模型.对齿轮泵的压力脉动进行了理论和仿真研究,求得了相同理论流量和转速及工作压力下的传统齿轮泵和四行星齿轮泵的压力脉动载荷.根据所求得的压力脉动载荷,采用Workbench软件对齿轮泵轴进行了瞬态和疲劳寿命分析.通过对比分析证明四行星齿轮泵的压力脉动减小10倍以上,齿轮轴的疲劳寿命提高280.7%~325%.
[Abstract]:Based on the flow pulsation characteristics of the four-planet gear pump, a corresponding mathematical model of pressure pulsation is established. The theoretical and simulation study on pressure fluctuation of gear pump is carried out. The pressure pulsation loads of traditional gear pumps and four-planet gear pumps with the same theoretical flow rate, rotational speed and working pressure are obtained. The transient and fatigue life of gear pump shaft is analyzed by Workbench software. It is proved that the pressure pulsation of four planet gear pump is reduced by more than 10 times, and the fatigue life of gear shaft is increased by 280.7 and 325 times.
