Abstract: This study evaluates different frequency domain vibration fatigue methods by verifying the results of the analyses with the experimental data on the bracket of an electrical panel mounted on a military vehicle. Loadings are defined considering composite wheeled vehicle vibration exposure as stated in the MIL-STD-810G Standard. The electrical panel and the bracket are simulated by FEM. Response PSDs are created on critical points. The experiment is carried out by using a uniaxial electrodynamic shaker. In this study, the Dirlik method proposes the most reliable and accurate fatigue life, while the Wirsching-Light method overestimates. Ortiz-Chen has made a very conservative prediction among other methods in this case study.
