摘要
为分析电控伺服油共轨系统的动态性能和不同参数对系统性能的影响,以瓦锡兰RT-flex60C柴油机伺服油共轨系统为对象,研究伺服油轨系统的结构特点和工作原理。建立系统主要部件的数学模型,采用SIMULINK仿真软件对伺服油共轨系统进行仿真,通过仿真实验分析伺服油泵转速、收集器和共轨容积、柴油机负荷对伺服共轨管压力波动产生的影响,分析得出收集器和伺服共轨容积对轨压有比较大的影响,因此建议在满足柴油机工作性能的基础上,选用较大的收集器容积或分段式伺服共轨管。
Wartsila RT- flex 60C diesel engine is selected as the research object to analyze the characteristics of servo oil common rail system. The system simulation model is built, and various mathematical model of the system is designed. 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 module. The volume of collector and servo oil common rail has greater effect on fluctuation of servo oil common rail system pressure. It is suggested that a greater collector volume or a segmented servo oil common rail tube be used to satisfying the performance of servo oil common rail system.
