Abstract: The main objective of this research work is to find the mode shape and corresponding natural frequency of a space frame chassis. Finite element analysis is used to find the mode shape and frequency. In order to simplify the analysis process only chassis frame of a sports car has been considered and complex assemblies has been avoided. CATIA V5 has good modeling features with lots of facilities for design. The model of space frame chassis has been prepared in CATIA V5. For analysis FEA based software ANSYS 14.5 has been used. The body shape is fixed and it is not subjected to any change in design parameters for the present study. The frame consist of 95 body parts and it is divided in three major parts known as boot space, driver cabin and engine chamber. The engine chamber can accommodate variety of engines without major change. The results shows that the frequency range varies from (130.49- 228.48) Hz.

Abstract: 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 s
