摘要

以7RT-flex 60C柴油机为研究对象，以流体力学中连续性方程和运动方程为理论依据，针对系统中伺服油泵、收集器、伺服油共轨管和排气控制模块等建立分块数学模型，分析伺服油共轨系统的特点.利用MATLAB/Simulink对所建模型进行数值计算求解，实现针对收集器与伺服油共轨管轨压、伺服油泵柱塞行程、柱塞腔压力与流量等动态仿真及参数分析.仿真曲线及数据与实际系统基本特性的比较验证了所建模型的正确性.

Abstract

7RT-flex 60C diesel engine is selected as the research object to analyze the characteristics of common rail system. Based on the continuity equation and the motion equation of the fluid mechanics, the mathematical model with blocks is established on servo pumps, collector, common rail pipe of servo oil and vent control module, etc. All the mathematical models are calculated by MATLAB/Simulink to achieve the dynamic simulation and parameter analysis on the collector and servo oil common rail pressure, servo pump plunger stroke, pressure and flow rate of plunger hole, etc. Comparison of simulation results of curve and data with the basic characteristics of actual servo oil common rail system verifies the correctness of the proposed model.

Key words： electronically controlled diesel engine; servo oil; common rail system; simulation
