Abstract:
According to the high damping characteristics of shape memory alloy(SMA),the energy analysis method was applied to the single-degree-of-freedom inerter-based system.The restoring force of SMA was derived through the relationship between free energy function and dissipation function.The time and frequency responses of SMA were calculated and analyzed.Since the parameter of inerter is irrelevant to the mass,the relevant parameters can be analyzed without changing the mass,and the parameter optimization can be realized through the contour map of resonance peak projection.The results show that the reasonable parameters can make the inerter have better vibration reduction effect,so as to achieve the optimization goal.
