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 presents a stiffness - damping mechanical automatic adjustment tractor seat suspension system solutions. As long as the parameters are chosen reasonably, the equivalent stiffness and equivalent damping of the system can be automatically adjusted according to the different weight of the driver to keep the natural frequency of the system constant, so as to achieve the best match between the seat suspension parameters and the driver’s different weight.
