A comparison of vibration behavior of linear and nonlinear bus driver seat suspension system using the 5DOF model
Vibration of the driver's seat suspension is analyzed using a 5DOF model. The seat's suspension system includes an air spring and hydraulic damper having nonlinear behavior determined experimentally. The random excitation y r (t) is simulated with ISO 8608 standard through the floor vibrat...

| Summary: | Vibration of the driver's seat suspension is analyzed using a 5DOF model. The seat's suspension system includes an air spring and hydraulic damper having nonlinear behavior determined experimentally. The random excitation y r (t) is simulated with ISO 8608 standard through the floor vibration acceleration obtained with the device VM31. Operating parameters include vibration isolation ability SEAT (%), comfort level a w (m/s 2 ) (ISO 2631:1-1997), and vibration's effect on health A(8) (2002/44/EC). At an average speed of 48 (km/h), the a w values of body parts in the linear case are larger than in the nonlinear case, precisely 32%, 40%, 33,5%, and 35,5% in the head, pelvis, upper torso, and lower torso, respectively. SEAT value reaches 93,5% and 74,1% for the linear and nonlinear cases, respectively. |
