刚度-阻尼机械自动调节式拖拉机座椅悬架系统的研究

Research of Tractor Seat Suspension System with Automatic Stiffness-dumping Adjustment

本文提出一种刚度-阻尼机械自动调节式拖拉机座椅悬架系统的方案。只要合理选择参数,便可根据驾驶员的不同体重自动调整系统的等效刚度和等效阻尼,保持系统的固有频率不变,实现座椅悬架参数与驾驶员不同体重的最佳匹配。

This paper introduces a new design method for tractor seat suspension system which can realize automatic adjustment of the stiffness-dumping. If the related parameters are reasonably selected based on the driver's weight, the equivalent stiffness and the equivalent dumping of the system can be automatically adjusted to keep the inherent frequency of the system constant. As the result, the best match between the seat suspension parameters and the driver's weight can be achieved. The contrast test between the ordinary seat and the new type seat shows that the seat's comfortable characteristic for driver has been improved singnificantly.
