| Research Abstract |
In this research work, the vibration characteristics and braking performances were analyzed for high speed tractor-implement systems. The natural frequencies on tractor chassis for rotational and translational motions were analyzed by using Campbell diagram and phase of each acceleration waves in time domain. The vibration characteristics of operator seat on the several road conditions were also analyzed. Furthermore, the braking performances were analyzed for the tractor itself and tractor-trailer combinations. Consequently, the several valuable data on agricultural safety and comforts for the tractor operators were obtained.
