摘　　要：通过利用等效圆盘等效轴法建立了两自由度的柴油机瞬时转速模型,并对其进行了仿真计算,由此得到了柴油机空车不同转速下和柴油机转速为1500r/min、不同负荷工况下的仿真结果,较为精确地揭示了瞬时转速的变化规律,为利用瞬时转速对柴油机进行状态监测以及故障诊断提供理论上的基础。The two degrees of freedom model of the transient speed for a diesel engine is built based on the equivalent disk equivalent axis method.With the model we make a simulation. The simulation results under the diesel engine idling at diffierent speeds and running at 1500r/min with different loads are given in this paper.It opens out the fluctuating rule of the transient speed and provides the theoretic basis for the state monitoring and diagnosis based on transient speed of a diesel engine.
