Applicability study of Steinberg vibration fatigue model in electronic products

In the vibration environment, electronic products may have fatigue failure, which affects its reliability level seriously. Therefore, it is important to estimate the vibration fatigue life of electronic products. The common used vibration fatigue model is Steinberg model which is necessary to be studied. This paper analyzes the derivation of Steinberg vibration fatigue model. Assumptions and simplifications of the model and the influence of parameters on the vibration fatigue life are studied. Finally, the applicability of the model and vibration design guidelines of electronic products are summarized. It provides a basis for the improvement of vibration design.
