In combination with dynamic balance practice,we deal with some problems existing in the influence coefficient method,for example,excessive hangover vibration and inadequate balance weighted mass match,and propose the following three ameliorative methods: weighted iteration least-squares method,restrained mass match least-squares method and genetic algorithm-based least-squares method.
