摘要
针对航空发动机转子静、偶不平衡量控制方法开展研究,基于坐标变换原理,以转子不同心度满足设计要求为约束条件,以转子静、偶不平衡量线性加权和最小为优化目标,提出了一种转子不同心度与不平衡量的计算方法,应用该方法对某型发动机的风扇转子进行了分析,表明该工艺方法能够明显改善转子不平衡量,达到控制转子静、偶不平衡量的目的。
Aiming at the control method of static and couple-unbalanced quantity of aeroengine rotor, based on the principle of coordinate transformation, with the rotor's different heart rate meets the design requirements as the constraint condition, with the rotor static and couple-unbalanced quantity linear weighting and minimum as the optimization goal, this paper proposes a calculation method of rotor concentricity and unbalance. The method is applied to analyze the fan rotor of a certain engine, which shows that the method can significantly improve the rotor unbalance and achieve the purpose of controlling the static and couple-unbalanced quantity of the rotor.
