基于Creo软件的刚性转子平衡问题研究

Study on the balance problem of rigid rotor based on Creo

分析刚性转子平衡的机理,并对偏心转子的离心惯性力及惯性力矩进行了理论计算。基于不平衡校正的减去质量法,利用Creo软件对刚性转子的静平衡和动平衡进行了优化设计。优化后转子支撑处的离心惯性力及惯性力矩均为0。这一结果表明,利用Creo软件对刚性转子进行平衡问题研究完全可行,结果正确。

In order to study the balance problem of rigid rotor based on Creo,the mechanism of rigid rotor balancing is analyzed,and the centrifugal inertia force and moment of inertia of an eccentric rotor are calculated theoretically.Based on the unbalance correction of“subtracting mass method”,Creo is used to optimize the static and dynamic balance of the rigid rotor.After optimization,the centrifugal inertia force and moment of inertia at the rotor support are both 0.The results show that it is feasible and correct to use Creo to study the balance problem of rigid rotor.
