Abstract

Abstract: According to the 1/4 body-seat vertical vibration model of high-speed rail, an optimal design simulation model for damping ratio of seat suspension was established. An optimal design mathematical model for damping ratio of seat suspension was built with the optimal ride comfort as the target. Taking the track vertical irregularity as input and the seat suspension vertical stroke as constraint condition, an optimization design method for damping ratio of seat suspension based on track excitation was presented. With a practical example, the damping ratio was designed and validated by simulation. The results show that the damping ratio value design method can effectively improve ride comfort.
