Fatigue Damage Severity Calculation for Vibration Tests

CODEN: JTEVAB

Abstract

An analytical solution to calculate a fatigue damage spectrum for a linear single degree-of-freedom system is presented to assess fatigue damage severity for various vibration test specifications. This solution can be served as the fundamental to develop an accelerated vibration test specification based on the real measured customer usage data and the use of material. Fundamentals of vibration characteristics for sinusoidal and random vibrations are well described in this paper. The state-of-the-art frequency-based fatigue theories are also reviewed. Finally, this paper compares the calculation results for a product subject to the vibration loads defined in IEC-60068-2-6 and ISO 16750-3.
