| 中文摘要: |
| 对不同温度工况下的电泵流体域进行流体仿真，确定油温对泄漏量的影响。应用流固耦合（FSI）分析的方法，对极限工况下电子泵壳体与端盖间结合面压进行仿真计算。将仿真结果用于电子泵密封性的评价。分析结果表明：电子泵壳体与端盖结合面密封性不足，存在泄露泄漏风险。针对密封性不足区域的设计提出改进意见，以减少电子泵工作泄漏量，提高工作效率 |
| 英文摘要: |
| The fluid field of E pump under different temperature conditions was simulated, to make sure the influence of temperature to leakage. Fluid structure interaction(FSI) method was applied to calculate the contact surface pressure between E pump housing and cover under ultimate working condition. The simulation results were used to evaluate the sealing of E pump. The calculation results showed that: the sealing of contact surface between E pump housing and cover was insufficient, existing leak risk.Some improvement suggestions were proposed aiming at sealing shortage area, in order to reduce E pump sealing and improve working efficiency. |
