高速复杂形状簧片阀动力学模型的研究

STUDY ON THE DYNAMIC MODEL OF HIGH-SPEER REED VALVE OF COMPLICATED SHAPE

高速复杂形状簧片阀是微型发动机关键零件之一。由于功能要求不同 ,其形状不同。本文从热力学着手 ,首先探索了阀隙马赫数对发动机压缩过程绝热指示效率的影响 ;然后对复杂阀片进行了分析 ,建立了受迫振动模型。

Reed valve,high speed and complicated in shape,is one of key parts in microengine.Different demends of function will lead to the difference in its shape.In this paper,discuss the mach number′s effect of valve′s aperture on adiabatic indication efficiency during the process of compressing of engine according to thermodynamics;analyze the complicated reed valve and make the model of passive vibration.All this lay a better foundation for design and application of reed valve.
