Abstract

The main consideration of any design is that it should be structurally safe. But electronic devices which are input to mechanical drives are used in large industries and ships, where it may expose to vibrating environment. Also they may expose to vibration while transporting through road or sea. In such cases, simple structural analysis is not enough to say whether the design is safe. Here lies the importance of vibration analysis. This can be done using the software Ansys Workbench. The cabinet for electronic devices is modelled in PTC Creo 2.0. For deciding whether the cabinet of electronic device is safe in vibrating environment, the analyses carried out are modal analysis and harmonic analysis. In case of shock loading, response spectrum analysis is also carried out to see whether the design is safe in sudden shock loads. Initially static structural analysis is carried out and design is found to be not safe. After making multiplestrengthened models, the bestdesignis considered forvibration analysis. After carryingoutvibration analysis, some components of the system were found to be having more stress and deformations in vibrations and shock loading. So such parts were strengthened again and vibration analysis is performed again on the new design. Finally, system was found to be safe for the required application.
