Comparative Study on Vibration Control of Engineering Vehicle Suspension System

The vibration of engineering vehicle during operation greatly increased driver´s labour intensity for the road condition is bad. Therefore, based on the PID control and adaptive fuzzy PID control, the paper establishes semi-active suspension model of engineering vehicle and compares vibration control and suspension performance among the semi-active suspensions, taking engineering vehicle as the study object. Through the further simulation research, from the comparative analysis performance indexes of riding comfort and handling safety, we can reach the conclusion that the control effect of adaptive fuzzy PID control improves by different degrees than the passive suspension and PID control suspension. The results show that adaptive fuzzy PID control suspension can reduce the vehicle vibration commendably.
