Temperature Response Characteristics of Various Vibration Isolators

Four types of vibration isolators were characterized to determine whether the system using them could survive Arctic operation. Previous operation in a desert environment had been performed without difficulty. It was predicted that Arctic operations would be successful based on desert and laboratory information. Data at various temperatures were gathered in the lab, and power spectral density (PSD) data, transfer functions, and fatigue ratios were used to predict responses at Arctic temperatures. Predicted Arctic responses exceeded desert responses in some frequency regions, and it was determined that additional testing at Arctic temperatures was warranted.
