Abstract: In this work the performance evaluation of vibration analysis on the battery tray is carried out and checked for sustainability under severe operating conditions using finite element analysis. The battery tray consists of cells and electrical wiring which is used for the torpedo’s battery backup, which requires stability under sailing. The battery tray is modeled with Pro Engineer software. This model in IGES format is imported to HYPERMESH version V11 for development of converged mesh. The meshed file is then imported to ANSYS V14 and the analysis is performed. The shock and vibration on the tray is performed with the input parameters such as g loads, frequency and acceleration/amplitude’s then static, modal and harmonic analysis results obtained from the ANSYS FEA software is compared with that of experimental predictions.

Keywords: Battery tray, modal frequencies, frequency response, dynamic stability
