279 Engineering Design about Electro-Hydraulic Intelligent Control System of Multi Axle Vehicle Suspension

Based on the dynamics analysis and testing about the multi axle vehicle electro-hydraulic intelligent suspension model, the optimal damping ratio control method was given in the paper. According to the character of suspension control objects and the influence factors of the vehicle ride comfort performance, the distributed not real-time suspension control system project was given. In the paper, the hardware and the software of intelligent suspension control system were designed which were used in the multi axle vehicle test. At last, the test result has proved the suspension control system designed in the paper of excellent effect and reliability, which can improve the vehicle vibration environment and make sure that the control system could be well applied.
