Abstract

The vibration of truck-mounted concrete pump booms during concrete pouring process will result in fatigue failure and even fracture, imprecise positioning, and shortening lifespan, et al. This paper aims to study the vibration control strategy for truck-mounted concrete pump booms in order to reduce/eliminate the booms vibration by combining the booms with pump unit completely. First, the mathematical models of hydraulic system of booms and pump unit are established respectively, and the dynamic characteristics of booms and pump unit are analysed independently. Second, the reason and influence factors of vibration of truck-mounted concrete pump booms are analyzed. Then, the vibration control strategy for truck-mounted concrete pump booms is proposed, and a numerical model is established to identify the validity of the vibration control strategy. The research findings offer a new powerful tool for dealing with the issue of vibration control for truck-mounted concrete pump booms and other rigid-flexible coupling machinery.
