摘要
Abstract
A novel four-stage damping adjustable hydraulic interconnected suspension(FDAHIS)system is proposed.In this system,two solenoid on-off valves with different normal hole areas are connected in parallel to the damping valve of a passive hydraulic interconnected suspension(HIS)system.The solenoid valve's operational states,either open or closed,are controlled by the feedback control strategy,regulating the hydraulic flow to enable four-stage damping adjustment.In order to study the system performance,models for both the FDAHIS system and a 7-DOF vehicle are established.The model is validated through bench testing of the system.The vehicle simulation results show that the FDAHIS system performs better in ride comfort and anti-pitch performance than the passive HIS system.关键词
