摘要：

This study investigates the impact of whole-body vibration (WBV) in terms of daily vibration exposure (A(8)) at seat-pan, weighted acceleration response (Awz) at seat-base, and Health Guidance Caution Zones (HGCZ), and vibration damping ratio (VDR) among three tractor drivers. Three ride conditions were considered i.e., average forward speeds (5-Levels), road roughness (5-Levels), and two driving postures (sitting vertically erect with a backrest position (P1) and sitting freestyle with no backrest contact (P2)) utilised to arrange the experiments by response surface methodology (RSM) design. The total vibration (av) was observed from 0.62-1 m/s2, 0.6-0.94 m/s(2), and 0.49-0.9 m/s(2) for tractor drivers (TD) 1, 2, and 3, respectively. Optimised ride conditions were average speed (6.37 m/s), road IRI (2.28 m/km), and P2 among all the selected drivers. Moreover, the best suitable linear regression model is found with 97.73% and 97.57% desirability for drivers first and second, respectively.
