A new shaft multi-objective optimization dynamic balancing method based on differential search algorithm

摘要

Combined with the influence coefficient methods and the Holo-balancing theory of shaft system, a new shaft multi-objective optimization dynamic balancing method including energy, uniformity and maximum of the residual vibration is proposed by building a multi-objective fuzzy evaluation function and application of Differential Search (DS) algorithm.The advantage of DS algorithm is studied by comparing with four other optimization algorithms.And the principle of balancing weight optimization of DS algorithm is studied to realize the shaft dynamic balancing.Finally, the validity and effectiveness of the proposed method is verified through a field power generator set balancing case.
