| 摘 要： | 针对某型船用高速柴油机高压共轨燃油系统轨-器连接高压油管压力波动大的现象，利用AMESim液力仿真平台搭建共轨系统模型，开展压力波动峰值影响因素研究。在此基础上提出降低压力波动峰值的结构改进方案，并对优化方案进行试验验证。结果表明:在共轨管出口设置阻尼孔并优化油管内径,可有效降低轨-器油管压力波动峰值。

| Abstract: | Aiming at the phenomenon of high pressure fluctuation in the rail-injector connecting fuel pipe of the high pressure common rail system of a marine diesel engine, a simulation model of the common rail was built with the AMESim hydraulic simulation platform to study the influence factors of the pressure fluctuation peak. Based on the analysis results, the structural improvement scheme to reduce the pressure fluctuation peak was proposed, and the optimized scheme was tested and verified. The results show that the pressure fluctuation peak can be effectively reduced by arranging a throttling hole at the common rail outlet and optimize the inner diameter of pipe. |
