Abstract

Transmission gearbox housing is subjected to noise and vibration induced by internal harmonic excitation. The internal harmonic excitation produces a dynamic mesh force, which is transmitted to the housing through the shafts and bearings and causes transmission failure. The main objective of this research work is to study the relation between the transmission vibration and the positional fixed constraints of vehicle frame by comparing the free vibration results of zero displacement constraint condition to positional constraint of the different number of connecting bolts. The vehicle gearbox housing is mounted on vehicle frame using connecting bolts fixture. The present design of heavy vehicle truck transmission housing is mounted on vehicle frame using 37 connecting bolts on five different positions. The study has been completed in two parts, in first parts all 37 connecting bolts were fixed on vehicle frame and in second part of study the front and bottom positional bolts were loosened to study the relation between vibration and constraint connecting bolts. Reciprocity Principle was used to apply the loads on housing. The first 20 vibration mode shape and natural frequencies were calculated using ANSYS 14.5. The study has theoretical and practical importance for the structure optimization of gearbox housing. ANSYS 14.5 is used as FEA based analysis tool. The natural frequency for zero displacement condition varies from 1669 Hz to 3576 Hz and for loose transmission housing frequency varies from 750 Hz to 3802 Hz. The analysis results is verify with experimental results available in literature.
