Tractor driving causes comfort and spinal problems due to low-frequency vibrations. For these reasons suspension systems have been adopted in order to limit the vibration transmitted to the driver. However, it has been shown that despite the use of traditional devices like suspensions on the axles, on the cab and on the seat, the level of vibration in some operations is higher than the vibration level limit prescribed by the Directive 2002/44 /CE. The vibration may be reduced through semi-active cab suspension system. The purpose of this research is to develop a specific control system for tractor cab semi-active suspensions in order to reduce the level of vibration compared to traditional suspensions. The analysis of the results shows that the designed control produced a reduction in the level of vibrations transmitted to the driver and an increase in the driving comfort.

Abstract

Tractor driving causes comfort and spinal problems due to low-frequency vibrations. For these reasons suspension systems have been adopted in order to limit the vibration transmitted to the driver. However, it has been shown that despite the use of traditional devices like suspensions on the axles, on the cab and on the seat, the level of vibration in some operations is higher than the vibration level limit prescribed by the Directive 2002/44 /CE. The vibration may be reduced through semi-active cab suspension system. The purpose of this research is to develop a specific control system for tractor cab semi-active suspensions in order to reduce the level of vibration compared to traditional suspensions. The analysis of the results shows that the designed control produced a reduction in the level of vibrations transmitted to the driver and an increase in the driving comfort.
