STUDY OF DYNAMIC CHARACTERISTICS CONCRETE PUMP BOOM

Abstract

The truck mounted concrete pump is the most efficient tool for working with concrete mixtures in the construction of high-rise structures. With the development of construction technology, ever higher technical requirements are placed on the boom of a concrete pump in terms of dynamics and control. In order to study the dynamic characteristics of the boom system, three dynamic models were built in this work, such as a model with several rigid links, a rigid-flex coupling model, and a rigid-flex coupling model with an equivalent hydraulic cylinder. Simulation analysis and experimental analysis have been carried out, and they show that we must not only take into account long-range movement, but also take into account small flexible deformation in order to accurately study the dynamic characteristics of the boom system. It provides a theoretical framework for vibration control, trajectory prediction, and lifetime estimation for the boom system and such structures.
