Abstract

Mechanical and electrical components can be vibration isolated from the chassis or panels to which they are mounted, by cutting the chassis at the component mounting points to form cantilever beams. The dimensions of the beams are chosen to give an appropriate resonant frequency to the spring-component mass system to provide the required vibration isolation. By preventing or reducing the transmission of component generated vibrations into larger area panels, radiation of audible noise can be greatly reduced.

Flexible Mounting for Vibration Isolation

Mechanical and electrical components can be vibration isolated from the chassis or panels to which they are mounted, by cutting the chassis at the component mounting points to form cantilever beams. The dimensions of the beams are chosen to give an appropriate resonant frequency to the spring- component mass system to provide the required vibration isolation. By preventing or reducing the transmission of component generated vibrations into larger area panels, radiation of audible noise can be greatly reduced.

This isolation method maintains metal to metal contact for electrical grounding and dimensional stability, uses no additional space, uses existing material and provides an easily adjustable spring rate. The drawing illustrates a power supply incorporating the isolation method.
