Abstract
Accelerometers see applications in a range of industries, frequently seeing installation on spacecraft ahead of thermal testing before dynamic testing. However, the current studies and specifications see minimal investigation of the effect of thermal cycling on shock and vibration accelerometers. This paper details a multi-stage and phase testing profile. The testing profile and methodology used throughout this work enabled a comparison of two different accelerometer types (vibration and shock) as well as an investigation of the sensitivity-temperature dependency of each model of accelerometer. Sensitivity analysis following the testing shows all accelerometers survived and continued to function correctly after being held at steady state extreme high and low temperatures. However, after the extended cycling, some accelerometers exceeded the allowable ±5% deviation limits on sensitivity.
