Abstract
Topaz II is a Russian made nuclear powered satellite purchased by the United States. This thesis provides a vibration analysis of the power unit of Topaz II. Several experimental vibration tests were conducted on the actual power unit by Sandia National Laboratories, in Albuquerque, New Mexico. Utilizing Structural Dynamics Research Corporation's I-DEAS software, this model was tested using the same vibration test values as those performed on the actual power unit. The lateral and axial, experimental and theoretical, sine tests were then analyzed. The purpose of this analysis was to determine how accurate a representation the model was of the actual Topaz unit. This was accomplished through comparison of natural frequencies obtained experimentally with those predicted from I-DEAS testing of the finite element model. The frequency range of interest was from 0 Hz to 200 Hz. When solved for system modes, the model predicted all natural frequencies within 4.6 Hz of those found experimentally. The average variation between theoretical predicted and experimental determined natural frequencies was 1.8 Hz.
