The invention discloses a negative stiffness seat suspension based on double rollers, a parameter setting method and a storage medium thereof in the technical field of seat suspensions, a mechanism of the seat suspension is composed of a vertical air spring and a negative stiffness mechanism, the vertical air spring mainly plays a role in supporting a load, and the negative stiffness mechanism comprises spring sleeves which are oppositely arranged; the horizontal spring is arranged in the spring sleeve, the small roller is connected with one side of the horizontal spring and is installed through a small roller connecting rod, and the large roller is arranged on the large roller support. The overall rigidity of the system is adjusted through negative rigidity, so that the system has good static bearing performance and dynamic vibration isolation capacity; the inherent frequency of the system design is low, and the low-frequency vibration isolation effect is good; according to the system, the vibration response amplitude can be effectively reduced, the vibration attenuation time is shortened, and the comfort of the seat is improved.

    本发明公开了座椅悬架技术领域的一种基于双滚子负刚度座椅悬架、参数设定方法及其存储介质,座椅悬架的机构由竖直空气弹簧和负刚度机构组成,竖直空气弹簧主要起支撑载荷的作用,负刚度机构包括对向设置的弹簧套筒,设置在弹簧套筒内的水平弹簧、水平弹簧一侧连接的通过小滚轮连杆安装的小滚轮、大滚轮支架、设置大滚轮支架上的大滚轮以及底座。本发明采用负刚度调整系统整体刚度,使其具有良好的静态承载性能和动态隔振能力;本发明的系统设计的固有频率较低,低频隔振效果较好;本发明的系统能有效减小振动响应幅值,缩短振动衰减时间,改善座椅舒适性。
