摘　　要：传统的柴油机设计周期较长且主要依靠经验公式,难以保证设计的精确性。使用计算机模拟软件可以解决这些问题。使用GT-power一维模拟软件对某机型中速柴油机建立仿真模型。通过对模型的计算,得出相关柴油机性能主要参数的模拟结果并与实验值进行对比。进而通过调整模型相关参数,对充量系数、油耗等参数进行优化,为该柴油机设计提供依据和参考。Traditional method of diesel design needs a very long period and it is hard to achieve accuracy.But computer simulation software can solve the problems above.In this paper,the software named GT-power is used to simulate the performance of medium-speed diesel engine.Through the calculation to the model,key parameters of the diesel can be achieved,then be compared with the experimental value.If the gap is small,the related parameter can be changed to optimize the volumetric efficiency,fuel consumption and so on.Finally,some guide and reference is provided for diesel design.
