一、概述谐振是电子设备隔振技术中颇感棘手的问题。当谐振发生在扫频激振的低频段时,如果隔振系统的阻尼比较小,则系统的响应振幅将很大。一旦电子设备与机架之间的自由运动空间或隔振器本身允许的自由运动空间较小,则可能因为响应振幅大于许用变形空间而使设备
I. Overview Resonance is a very difficult problem in vibration isolation technology of electronic equipment. When the resonance occurs in the low frequency range of the sweep excitation, if the damping of the vibration isolation system is relatively small, the response amplitude of the system will be large. Once the space for free movement between the electronics and the gantry or the free movement space allowed by the isolator itself is small, it is possible that because the response amplitude is greater than the allowable deformation space, the device
