Optimization of Massey Ferguson Tractor Seat Angle Inclination by Finite Element Method

Total activity that is performed by the operator on the tractor seat, affects driver comfort, especially when the critical pressure distribution is in the region of buttocks, so driver posture plays an important role in comfort. Thus, research to model and optimize the angle of inclination of Massey Ferguson tractor seat in ABAQUS finite element software, in order to validate the seat modeling ,output results were compared with experimental results. In this model the tractor seat with five angles of 0, 5, 10, 15, and 20 degrees in the four stimulation acceleration 0.5, 1, 1.5 and 2 meters per second squared in frequency range of 3- 66 Hz was forced vibration and output accelerations in the contact areas of driver's body with seat in three different mass of Iranian Agriculture drivers were obtained from the finite element software .The results of the main factors and the interaction effects in mean variance analysis table on output acceleration in contact areas showed a range of angles of 10 to 15 degrees has been optimized for Massey Ferguson tractor seat, Because these angles in all contact areas of driver's body with seat has not big effect in creating uncomfortable.
