    • One embodiment provides a system that mitigates vibrations caused by cooling fans in a computer system. More specifically, the system includes a cooling fan mechanically coupled to the chassis of the computer system, wherein vibrations generated by the cooling fan are coupled to the chassis. The system also includes an actuation mechanism that creates a relative displacement between the cooling fan and the chassis when a control signal is applied to the actuation mechanism. The system additionally includes a detection mechanism which detects the relative displacement and generates a feedback signal which represents the relative displacement. The system further includes a control signal generation mechanism which converts the feedback signal into the control signal, which is subsequently applied to the actuation mechanism. When the control signal is applied to the actuation mechanism, the relative displacement between the cooling fan and the chassis vibrationally decouples the cooling fan from the chassis.
    • 一个实施例提供了一种减轻由计算机系统中的冷却风扇引起的振动的系统。 更具体地,该系统包括机械地联接到计算机系统的底盘的冷却风扇,其中由冷却风扇产生的振动耦合到底盘。 该系统还包括致动机构,当致动机构施加控制信号时,致动机构在冷却风扇和底盘之间产生相对位移。 该系统还包括检测相对位移的检测机构,并产生表示相对位移的反馈信号。 该系统还包括控制信号产生机构,其将反馈信号转换成控制信号,该控制信号随后被施加到致动机构。 当控制信号被施加到致动机构时,冷却风扇和底盘之间的相对位移使冷却风扇与底盘振动地分离。
