The main objective of this research work is to find the natural frequency and mode shape of truck transmission housing. Truck transmission housing or gearbox transmission casing is subjected to vibration induced by the excitation forces transmitted to the casing through bearings. So it is required to find the natural frequency for the accurate prediction of housing life and prevent it from fracture. Housing is made of various materials like cast iron and Al alloys. In present few composites are also available for the manufacturing of casing. The vibration analysis of transmission housing was performed by finite element simulation using ANSYS 14.5 software. The vibration mode shapes for first twenty modes were studied. The results show that the natural frequency of vibration varies from 1306.3 Hz to 3879 Hz. The analysis results were verified with experimental result available in literature. Solid Edge software is used for the designing of transmission housing and FEA based ANSYS 14.5 software is used for the free vibration analysis of transmission housing.
