status of the SAE S-12 approach to <italic>VIBRATION ISOLATION</italic> of Aircraft Electronic Equipment

THIS PAPER outlines progress to October, 1958, on the new Shock and Vibration Manual. At that point, the methods of solving vibration isolation problems had been established. After further refinements and expansion, the manual will be issued by SAE Committee S-12 on Shock and Vibration.

The manual will set up procedures to be followed by engineers who don't have extensive experience in the field. It will give procedures for problems having up to six degrees of freedom.

The procedure, as described in the paper, now consists of three steps:

1. 1.
   Specification of the data required for the solution of a given problem.
2. 2.
   Calculating whether vibration isolators are needed.
3. 3.
   Determining the dynamic properties of the isolation system when the above step indicates isolation mounts are needed.
