Vibration analysis and control of 2SPS+SR suspension seat for improving vehicle ride comfort
Year: 2025
Type: article
Abstract: In order to minimize three-dimensional vibrations and improve the ride comfort of a construction vehicle, the 2-spherical-prismatic-spherical+spherical-revolute (2SPS+SR) parallel suspension seat is examined.The dynamic differential equations of the seven degree-of-freedom (DOF) vehicle and the seat model are derived.Under E-, F-, and G-level roads (classified based on standard or index, e.g., ISO 8608, for road roughness), the dynamic responses of the 2SPS+SR seat are analyzed.The simulation results indicate that the seat comfort performance using fuzzy-PID control is enhanced by 40.91 %, 19.84 %, and 36.40 %, which are compared with PID under E-, F-, and G-level roads, respectively.
