摘要
运用AVL EXCITE PU软件建立双缸机柴油机曲轴主轴承弹性流体动力润滑计算模型,计算分析了发动机最大扭矩转速下主轴承受力、最小油膜厚度、最大油膜压力、轴心轨迹等。结果表明,该双缸柴油机主轴承润滑良好,最小油膜厚度、最大油膜压力均在限值以内,符合设计要求。
AVL EXCITE PU software is used to establish a elastohydrodynamic lubrication model of a two cylinder diesel engine crankshaft,calculated and analyzed the main bearing forces,minimum oil film thickness,maximum oil film pressure,orbital path and so on.The results indicate that the lubricative performance of this two cylinder engine is satisfactory for us,for the results of the minimum oil film thickness and the maximum oil film pressure are below the extremum.
