Experimental Determination of Shock and Vibration Levels Inside the Safeguard PARB,

Abstract

Additional test data were sought to aid in application of the Dial Pack data and a series of vibration/impedance tests was conducted on both the model and the prototype. These tests consisted of vibrating points inside and outside the structures. Because the PARB is designed to remain elastic, it was possible to use the vibration data and linear theory to obtain impedance and transfer functions for various paths in the model and prototype. Using the knowledge gained from the model study and the vibration data from the prototype, impedance functions for the prototype were developed. This paper discusses the results of the impedance program, the validity of the data, and their extrapolation to predict internal vibration at high-frequency levels.
