This paper presents theoretical calculation, analysis and simulation (validation and verification) of driveshaft torsion vibration. The vibration measurement validation verification has been carried out on vehicle (4x2) having four cylinder engine 85kw@2800 rpm and six speed manual transmission for getting correlation between values of theoretical calculations and CAE results.
This analysis has been done in order to achieve vehicle good performance in terms of driving comfort as well as smooth functionality with zero vibration frequency at high speed. The propeller shaft series selection and refinement has been done using theoretical iteration with operating angle of prop shaft which exits in between the universal joint planes. A frequency of vibration analysis has evaluated at different propeller shaft layout and duty cycle.
The vibration performance predictions for vehicles with these design is rigorously done. The required parameters are recorded, compared in tabulated form shown in graphical way. The lowest operating angle of drive shaft design leads to optimize the vibration and provide better overall vehicle performance at different speed. An effective selection of drive shaft layout has been done by doing iterations on operating angle of universal joint. Thus the selected operating U-joint’s angles are input into actual drive line layout design to make it more realistic at zero vibration amplitude. The data is obtained by number of iteration done on vehicle validation as per duty cycle.
