摘要/Abstract

摘要： 利用复杂系统建模与仿真AMESIM软件建立电控单体泵燃油系统一维液力仿真模型，并进行了试验验证。通过对不同高压油管结构参数的燃油系统进行仿真研究，分析高压油管长度、内径及内壁粗糙度对单体泵供油压力、喷油压力及循环喷油量等燃油系统性能参数的影响。结果表明，高压油管结构变化引起系统高压容积、流通阻力、节流损失、流动损耗的综合作用是影响系统性能的主要原因，油管长度过长或内径过小会引起系统性能不规律变化。

Abstract: An one-dimensional hydrodynamic simulation model of electronic unit pump fuel system is established using AMESIM software, and the experimental verification is made for the proposed model. The effects of length, inner diameter and roughness high pressure fuel pipe structure on oil supply pressure, injection pressure and fuel injection quantity of electronic unit pump fuel system are analyzed through numerical simulation. The simulated results show that the structural change in high pressure fuel pipe leads to high pressure volume, flow resistance，throttling loss and dissipation of system, which affect the performance of fuel system. Irregular change in system performance would appear if the high pressure fuel pipe is too long or its inner diameter is too small.

Key words: ordnance science and technology, electronic unit pump, high pressure fuel pipe, high pressure volume, hydrodynamic simulation
