SOME SHOCK MOTIONS OF TWO DEGREE-OF-FREEDOM LINEAR SYSTEMS

Abstract

Damage sustained by equipment used in a moving carrier suddenly changing its velocity can sometimes be attributed to inadequate protective cushioning. Proper design of the protective cushioning can be realized by reducing the equipment and components to idealized mechanical systems and studying the responses as the system parameters are varied. This study considers the response to velocity shock with elastic impact. A set of design curves showing maximum acceleration of a flexible and vulnerable element of an equipment and the maximum deflection of the equipment's cushioning are produced using an analog computer. Additionally the computer's results are compared with analytical results for a few particular cases. The writer wishes to express his appreciation for the advice and assistance of Professor R. E.
