The Determination of Condition Met by Boom System Working in Safety Based on Multiple Load Case Analysis

Loads subjected by the boom system on the concrete pump are so complex, that fatigue cracks or fatigue fractures appear, which may lead to loss of property and casualty. However, when the concrete pump is functioning in safe condition, the damage of the boom system is reduced, thereby preventing the...

Summary:Loads subjected by the boom system on the concrete pump are so complex, that fatigue cracks or fatigue fractures appear, which may lead to loss of property and casualty. However, when the concrete pump is functioning in safe condition, the damage of the boom system is reduced, thereby preventing the accidents. In order to select safe working conditions, a boom system of 37m concrete pump as research object should be adopted. The finite element analysis is carried out on the boom system based on MSC. Patran and Nastran, with regularly varying degrees, and changing trends of the maximum stresses subjected by booms with the change of degrees of booms, attained a safe condition of the boom system. Finally, taking the four kinds of typical foundation casting working conditions as example, the feasibility of using this condition to determine the safe working condition has been verified.
