【摘要】 以索、缆、柔性杆类结构的振动控制为目标,研究了基于一种新型形状记忆合金(shapememory alloy,SMA)超弹性阻尼器的索振动控制。首先研究了SMA丝预拉伸对该种阻尼器性能的影响,然后对基于该种阻尼器的索振动控制进行了有限元模拟,最后进行了基于此种阻尼器的索振动控制实验研究。研究表明SMA超弹性阻尼器可有效控制索、缆、柔性杆类结构的振动。更多还原

【Abstract】 Cable vibration control was studied based on a new type of shape memory alloy(SMA) damper.Firstly,SMA wires’pre-tension effect of this kind of SMA damper was studied.Secondly,cable vibration control by the SMA damper was simulated by finite element method.Finally,cable vibration control effect by the SMA damper was tested.It is proven that vibration of the cable can be restrained obviously with the SMA damper by both the finite element simulation results and experimental results.更多还原
