摘　　要：提出了基于形状记忆合金(shape memory alloy,SMA)可控刚度支承的转子系统过临界转速振动控制方法,并试验验证了其有效性。首先,通过对SMA弹簧开展刚度测试得到弹簧的变刚度特性,建立SMA弹簧温度-刚度模型,设计了SMA变刚度支承结构。然后,提出了一种基于变刚度支承的转子系统振动响应控制方法,以带有多个变刚度支承的柔性转子系统为例,对支承的变刚度策略进行优化设计。最后,开展了基于SMA可控刚度支承的转子系统振动控制试验,过1、2阶临界最大振幅减振率分别可达到39.84%和57.93%,验证了转子系统支承刚度变化策略对过临界转速时振动抑制的有效性。A vibration control method for rotor systems at supercritical speeds based on shape memory alloy(SMA)controllable stiffness support was proposed,and its effectiveness was verified through experiments.Firstly,the variable stiffness characteristics of the SMA springs were obtained through stiffness testing,and a temperature stiffness model of the SMA springs was established.The SMA variable stiffness support structure was designed.Then,a vibration response control method for rotor systems based on variable stiffness supports was proposed,and the variable stiffness strategy was optimized and designed using a flexible rotor system with multiple variable stiffness supports as an example.Finally,vibration control experiments were conducted on the rotor system based on SMA controllable stiffness support,and the maximum amplitude reduction rates reach 39.84%and 57.93%when passing the first and second critical speeds,respectively,which verifies the effectiveness of the support stiffness variation strategy for vibration suppression of the rotor system at critical speeds.
