Abstract To study power flow transmission and active control of the frame structure under the influence of disturbance, firstly, the kinetic model of frame structure is established by wave method and the accurate dynamic response is obtained, then power flow transmission of structure is determined. The power flow is used as the objective function, and we will get optimized control force magnitude and phase by optimization algorithm, which is applied to the frame structure. Ultimately, active control of power flow for frame structure is realized. Based on active control method of power flow for frame structure, the numerical analysis and experimental validation is made. The results show that the dynamic response results of frame structure by wave method are accurate and reliable; Active control method of power flow can efficiently reduce the jitter of the frame structure in the whole frequency domain by numerical calculation and experiment research, and it proves that active control of power flow by wave method is right and valid.
