Abstract
The vibration of the agricultural machinery is very severe because of the rigid connection structure of the agricultural machinery and the bumpy road in the operating field which will cause the drivers' whole-body vibration, affect the drivers' comfort, aggravate the drivers' fatigue, and even endanger the drivers' health. Therefore, it is necessary to study the dynamic characteristics of the human body under different postures. Firstly, the vibration test platform is established according to the practical working conditions of the driver body. Then, vibration data of the human body under different postural statuses due to different upper torso inclination and bending of the legs are obtained on the vibration test platform. Finally, the effects of postural changes on human body dynamics are studied by analyzing the vibration frequency spectrum under different conditions. The results of this study can provide a significant reference for the design of the seat vibration damping system and the driver protection system of the agricultural machinery.
