Summary:

Wire rod is one of the important products of modern manufacturing. Laying head is widely used for wire rod coiling and storage. Rotors of laying head are typical rotating equipment in which vibration during operation is inevitable. To address the problem of achieving precise dynamic balance for the laying head rotor with complex and asymmetrical structures, a vibration test is performed on the rotor to determine its primary cause. Modal analysis is conducted on the laying head rotor using finite element analysis, with the critical speed calculated. Unbalance response analysis of the rotor is executed, coupled with the rotor structure to identify appropriate balancing planes. The rotor's three-dimensional model is used to calculate the distribution of the unbalance amount. The balancing process effectively decreased the rotor's eccentricity and vibration intensity with no significant increase in overall mass, meeting operational requirements. This method significantly increased balancing efficiency, compared to empirical balancing methods, without requiring multiple equipment startstop cycles. The balancing outcomes suggest that the proposed method is an effective and efficient solution for rotor balancing
