Research on Vibration Suppression for Boom Luffing of Telescopic Boom Aerial Work Platform

With the increase in the length of the boom for aerial work vehicles, the boom vibrates in rapid motion. Therefore, how to suppress the boom vibration and achieve good stability and safety is significant. Based on the research of telescopic boom aerial vehicles, the mathematical models of the link hydraulic system of telescopic boom aerial vehicles are established. According to the state equation of the boom system, the feedback gain vector is designed based on the linear quadratic optimal control theory, the feedback value is fed back to the signal input end of the solenoid valve to construct the closed loop control system which restrains the boom vibration, and the simulation of the closed loop control system is made to analyze the vibration suppression effect of the boom. Through the control of luffing motion, a vibration control method of telescopic boom aerial vehicle is put forward, which has a good reference function for similar products.
