高速平衡下大型储能飞轮转子系统的影响系数法研究

Research on influence coefficient method for large energy-storage flywheel rotor system at high speed balance

转子的不平衡所引起的振动是造成旋转机械故障的主要因素之一,动平衡技术是抑制或减小转子不平衡振动的重要措施。针对正在研发的大型储能飞轮转子系统,为了减少在高速运转时的不平衡,选取轮毂两端面为平衡平面,采用双面影响系数法对高速平衡下飞轮转子系统进行了研究,得到该转子系统双面不平衡量的分配,为大型储能飞轮转子系统的动平衡研究提供一种理论分析方法。

Vibration caused by rotor unbalance is one of the main factors of rotating machinery failure,while dynamic balancing technology is an important measure to suppress or reduce the unbalanced vibration of the rotor. In order to reduce the unbalance of large energy-storage flywheel rotor system under development in high-speed operation,two end faces of the hub are selected as the balancing plane,and the double-sided influence coefficient method is applied to study flywheel rotor system under high speed balance. The distribution of the two sided unbalance of the rotor system is obtained,which provides a theoretical analysis method for the dynamic balance of large energy storage flywheel rotor system.
