WT5”BZ]In this paper,the total vibratory power flow of multi wave types is studied.The extensional,flexural and torsional waves coexist within a shaft.The total vibratory power flow is chosen as the cost function in control of multi wave types.To achieve the control,the multi channel LMS control algorithm is applied.By computer simulation,the active control of multi wave types can be successfully achieved.
