Abstract

Boom vibration of concrete pump truck not only affects the running quality, but also increases the structure's stress and reduces its fatigue life. Based on Independent Modal Space Control method, experimental study on active control of boom vibration of concrete pump truck in horizontal position was carried out. Firstly, the flex-rigid multi-body dynamical model of boom system was established. Then an active control strategy was designed, which utilized a Modal Filter and optimal control theory to implement Independent Modal Space Control of boom vibration. Finally, the real-time control experiment was performed in which controlled oil-cylinders' movement provided the control force to reduce the boom's 1st modal vibration. Results show that the amplitude of the boom vibration can be lowered approximate 80% in horizontal position.
