Wire Rope Based Vibration Isolation Fixture For Road Transportation Of Heavy Defence Cargo

A fixture assembly has been designed for vibration isolation during transportation of heavy extra long cargo by road. The fixture is supported on numbers of heavy-duty metallic wire rope isolators. These isolators are very effective for both vibration and shock isolation and specifically developed for this application. The fixture has been designed based on static, modal and random analysis by finite element method. The strain measurement has been conducted on fixture for specified payload. Vibrations are recorded at various speeds on many locations for determining percentage isolation and system characteristics. The finite element analysis results and measured strain and vibration data are correlated for validation.
