双转子航空发动机转子动平衡研究

Research on Rotor Transient Equilibrium of Double Rotor Aircraft Engine

针对双转子动平衡存在的问题,在建立双转子系统的理论计算模型的基础上,给定一个转子的转速和两个转子的转速比,计算出在内、外转子上施加不平衡量后转子上任意一点的振动量,结合影响系数法,为双转子系统进行动平衡提供依据。

In view of double rotor transient equilibrium existence question, based on establishing theoretical calculation model of the double rotor system, the paper calculates vibration quantity on the. rotor＇s random point after exerting the equilibrium amount on inner -outer rotors, and also combining influence coefficient, provides the basis for the double rotor system＇s transient
