Vibration Fatigue Analyses of a Cantilever Beam in Transportation Based on Military Standard

Abstract

This study includes the vibration fatigue analyses of a cantilever beam exposed random vibration while transporting based on the specified military standard using Miner’s Cumulative Damage technique. The theory of Miner is introduced in detail. Finite element model is used to obtain the stresses on the designed cantilever beam under random vibration. Response Power Spectral Density is presented in graphical form at critical points. The fatigue life of the cantilever beam is calculated by using the stresses obtained by random vibration analysis.
