摘　　要：利用AMESim液压仿真软件建立电控柴油机喷油系统仿真模型,在此基础上,以喷油压力为优化目标,喷油量为约束条件,运用正交试验设计方法进行喷油系统参数仿真计算,再通过方差分析方法分析各参数对喷油压力的影响规律。研究结果表明,对喷油压力影响程度由强到弱依次为柱塞直径、油管直径、凸轮型线速度、喷孔数×喷孔直径(流通面积不变)、油管长度。通过方差分析得出最优参数组合方案为:喷油器喷孔数×喷孔直径为10×0.22 mm;凸轮型线速度0.46 mm/℃A;柱塞直径15 mm;高压油管长度800 mm;高压油管直径1.5 mm。此参数组令方案可以将喷油压力提高到154.3 MPa。Based on the established simulation model of electronically-controlled fuel injection system by AMESim code, the orthogonal test design method was employedto simulate for matching fuel injection system parametersby taking the fuel injection pressure as the optimization objective and the fuel injection quantity as the constraint condition, The method of variance analysis was then introduced to analyze the influence of the parameters on the injection pressure. The simulation result shows that the influence on the injection pressure from strong to weak is in sequence ofdiameter of plunger, diameter of high pressurefuel pipe, cam velocity, number of orifice × diameter of orifice （circulation area is constant） and length of high pressure fuel pipe; Results also reveal thatthe injection pressure can be enhanced to 154. 3 MPa based on the variance analysis when the fuel injection system parameters is 10 × 0.22ram - 0.46 mm/℃ A - 15 mm- 800 mm - 1.5 mm （ number of orifice × diameter of orifice-cam velocity-diameter of plunger-length of high pressure fuel pipe-di- ameter of high pressure fuel pipe）.
