Negative stiffness seat suspension based on double rollers, parameter setting method and storage medium thereof

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
