    摘要:

    为研究高原地区的低压环境对柴油机润滑系统各关键部位机油压力及流量的影响,利用AMESim软件建立某V型多缸柴油机润滑系统的仿真模型并进行校核,计算分析不同环境压力下润滑系统中机油压力的变化规律和各滑动轴承的泄油量变化规律。结果表明:在润滑系统的结构参数和运转参数保持不变的情况下,当环境压力降低时,润滑系统中机油泵出口、主油道入口、主油道末端及各滑动轴承等位置的机油压力随之线性降低;各滑动轴承的泄油量随着环境压力的降低略有升高,但升高幅度较小。

    Abstract:

    In order to study the oil pressure and flow on key parts of diesel engine lubrication system in lowpressure environment of the plateau region,a simulation model for a V type multicylinder diesel engine was established with the onedimensional simulation software AMESim.Based on the model,the oil pressure distribution of the lubrication system was computed and analyzed as well as the oil outflow amount of each bearing for different ambient pressure.The results show that,with the other parameters of the lubrication system remain constant,the oil pressure in the key place is reduced and the oil drain amount of each bearing is decreased slightly when the ambient pressure is decreased.
