Modelling, simulation and identification of a mobile concrete …

Abstract. Due to the light-weight construction of modern large-scale manipulators used, e.g., in mobile concrete pumps, the elasticity of the construction elements plays a significant role in the dynamic behaviour of the system. Therefore, current research is concerned with control strategies for active damping of elastic vibrations and trajectory

Estimation and control of the tool center point of a mobile …

Booms of modern mobile concrete pumps are vulnerable to elastic vibrations due to the light-weight construction. Although these vibrations can be effectively damped with appropriate controllers, the residual movement of the tool center point (TCP) during the pumping process is still uncomfortable for the workers guiding the end hose.

This is beacuse the force allignes with the joint between arm and boom, so the whole load is directly transfered to the boom. At 1,5m of depth, the boom cylinders push for 350kN. In this case the cylinders have a bore of 115mm and the same pressure of 34MPa, but work only pushing so the maximum force obtained from the previous source as before is of 365kN.

To enable a large operating range (up to approx. 60m) while being able to transport the boom on a standard truck, the boom of these mobile concrete pumps is constructed in a lightweight design. Due to the complex kinematics with up to 6 individual joints and the large working areas, an optimal manual operation by a human operator is cognitively not possible.
