seat suspension negative stiffness elements damping elements ride performance genetic algorithm
Three design modes of seat suspension, i.e., negative stiffness elements(NSEs), damping elements(DEs), and negative stiffness-damping elements(NSDEs), are proposed to evaluate the ride performance of a vehicle. Based on a dynamic model of a seat suspension and indexes of the root mean square deformation and acceleration of the seat suspension(xRMS)and driver’s seat(aRMS), the influence of the design parameters of the NSEs, DEs, and NSDEs on the driver’s ride comfort is evaluated. A genetic algorithm is then applied to optimize the parameters of the NSEs, DEs, and NSDEs. The study results indicate that the design parameters of the NSEs and NSDEs remarkably influence xRMS and aRMS, whereas those of the DEs insignificantly influence xRMS and aRMS. Based on the optimal results of the NSEs, DEs, and NSDEs, the damping force of the DEs is 98.3% lower than the restoring force of the NSEs. Therefore, the DEs are ineffective in decreasing xRMS and aRMS. Conversely, the NSEs combined with the damping coefficient of the seat suspension strongly reduce xRMS and aRMS. Consequently, the NSEs can be added to the seat suspension, and the damping coefficient of the seat suspension can also be optimized or controlled to further enhance the vehicle’s ride performance.
