Dynamic Simulation of Concrete Pump Truck's Boom System

The concrete pump truck's boom system of 5 booms is taken as the research object in this paper. Combined with finite element theory and multi-body dynamics theory, a rigid-flexible coupling model of concrete pump truck's boom system is established by modal synthesis method. With the measured displacement-time curve of turntable as the excitation, the booms' pumping process in horizontal

Fatigue life prediction for boom structure of concrete

Abstract. Frequent premature fatigue failure of construction machinery has spurred the demand for fatigue life prediction of such equipment. In this study, fatigue cracks were investigated in a concrete pump truck boom typically a high-strength steel plate welded box girder structure. The focus was two-tip corner cracks which frequently initiate at the weld toe between the top flange plate and the web plate …

Vibration Control of the Boom System of Truck-Mounted

Vibration of the boom system is inevitably caused by periodic disturbances, which are induced by pumping concrete. In this paper, an active control strategy of constant-position commandless input shaping technique is developed to suppress vibration. Based on a set of independent modal equations obtained by adopting modal approach, the double-impulse control with reverse direction is proposed
