Dynamic response and control strategy of energy dissipation and shock absorption structure under earthquake action

Aiming at the limitations of dynamic response analysis and control strategy of traditional energy dissipation and shock absorption structure under earthquake action, this paper adopts an improved energy dissipation and shock absorption design method and intelligent control strategy, aiming to improve the structure’s shock absorption effect, response accuracy, and adaptability. First, the structural response model is established by applying a multi-degree-of-freedom nonlinear dynamic model; second, the energy dissipation and shock absorption device is improved by using an adaptive viscous damper; then, an intelligent control strategy combining fuzzy logic control and a neural network is used; finally, accelerometers and displacement sensor devices are used to obtain structural dynamic response data in real-time for analysis and processing. The findings demonstrate that at the maximum displacement, the response error of the traditional shock absorption device is 44.44%, while the response error of the intelligent control is only 5.56%, which shows that the intelligent control strategy can effectively enhance the structural response accuracy. The method proposed in this paper can not only significantly reduce the impact of earthquakes on structures but also enhance the long-term stability and operation efficiency of structures.
