针对实际工程中锥阀经常出现振动、噪声等现象，通过设计实验观察振动情况，发现锥阀的振动是规律的周期振动。将CFD的计算结果同系统动力学模型的参数结合起来，对可能引起锥阀振动的原因如稳态液动力和瞬态液动力进行仿真分析。结果表明：稳态液动力并非引起锥阀发生周期振动的原因，瞬态液动力才是锥阀产生周期振动的原因。

The poppet valve always has vibration and noise problems in engineering. Through designing experiments,the poppet valve vibration was observed. It is found that the poppet valve vibration signal is a typical periodic vibration signal. Combining CFD re-sults with the system dynamic model's parameters,simulation and analysis about the effects of steady flow force and transient flow force to the poppet valve vibration were made. From the simulation results and theoretical analysis,it is found that the steady flow force is not the reason of valve periodic vibration,and the transient flow force is the main reason of poppet valve vibration.
