TEMPERATURE RESPONSE CHARACTERISTICS OF VARIOUS VIBRATION ISOLATORS

Four types of vibration isolators were characterized to determine whet her the system using them could survive Arctic operation. Previous ope ration in a desert environment had been performed without difficulty. It was predicted that Arctic operations would be successful based on d esert and laboratory information. Data at various temperatures were ga thered in the lab, and power spectral density (PSD) dam, transfer func tions, and fatigue ratios were used to predict responses at Arctic tem peratures. Predicted Arctic responses exceeded desert responses in som e frequency regions, and it was determined that additional testing at Arctic temperatures was warranted.
