基于SMA的結(jié)構(gòu)隨機(jī)振動(dòng)控制研究
[Abstract]:Superelastic shape memory alloy (shape memory alloy,) is an ideal material for passive control of structural vibration due to its unique functional characteristics. At present, the research on the vibration control of structures by SMA dampers is mostly carried out under deterministic loads, and seldom involves random vibration excitation environments. This paper focuses on the theoretical study of random vibration of SMA dampers, which has important practical and theoretical significance. In this paper, the basic mathematical knowledge related to random vibration is introduced, and the random vibration responses of single and multi-degree-of-freedom structures are analyzed. Based on the hyperelastic properties of SMA, a new SMA self-reset damper is proposed. The stress-displacement curve of the damper based on the Graesser constitutive model is established, and a simplified mechanical model is proposed. By using the equivalent linearization method, the random vibration response formulas of single-degree-of-freedom structures controlled by SMA dampers under white noise and earthquake are derived, and the results of Monte Carlo simulation method and equivalent linearization method are compared through an example. The correctness of the equivalent linearization method is proved. By using the equivalent linearization method, the random vibration response of multi-degree-of-freedom structures controlled by SMA dampers under earthquake action is derived, which verifies the damping effect of the dampers.
