RATIONAL SHOCK MOUNT DESIGN, INVESTIGATION OF EFFICIENCY OF DAMPED, RESILIENT MOUNT.

Abstract

The concept of ideal, or optimum, shock mount behavior is developed and offered as a standard for use in judging the efficiency of real mounts. The behavior of a shock mount consisting of a linear spring in parallel with a linear, bilateral damping link in response to experimentally determined shipboard shock motions is predicted. Computations are made for natural frequencies ranging between 5 and 20 Hz and for damping ratios up to 60 percent of critical. The effect on mount performance of variations in natural frequency, damping ratio, and characteristics of the input motion is discussed. One way of improving the efficiency of the mount is discussed briefly. This type of mount is judged to be rather inefficient, but it does have the advantage of maintaining its equilibrium position.
