Finite Element Analysis Of Concrete Pump Truck Boom Hinge Point And System Optimization

Concrete pump truck is a concrete pouring equipment, concrete is pumpedto construction site mainly relying on the boom system. Concrete pump truckboom is not only the key to the design and manufacture, but also the main forcecomponent, generally designed to be box-shaped structure, reasonable design itor not, directly affects the reliability of the concrete pump truck, machinestability and weight while about the development of concrete pump truck.Therefore, the concrete pump truck boom finite element analysis, to optimizethe boom hinge point system is to meet the needs of the development of concretepump, the actual, viable, important research.Firstly, the article made a detailed presentation of definition，composition,classification, research status at home and abroad and its historical developmentboom system of the concrete pump truck, and the components, constructionscope, length, number of arm frame, winding way, connect institutions andluffing mechanism of concrete pump truck boom system are described in detail,and the concrete pump truck boom system suffered loads were analyzed toderive its strength formula. Secondly, using Solidworks software to build athree-dimensional model of a48m concrete pump truck boom system model, thesource of model size is based on mapping a particular mode of48m concretepump model which is a exhibitions model of a company. Using SolidworksSimulation software to make a finite element analysis of the three-dimensionalof the boom system to arrive at the boom system stress, strain and displacementsituations. Again, using Solidworks Motion established motion example anddesign example between adjacent arm frames of concrete pump truck boomhinge point. In each arm frames cylinder force in motion study obtained aminimum target for the optimization, to optimize the objective for each phasebetween the hinge points of the system. The optimized data can beparameter-driven three-dimensional model of the original model. Finally, usingSolidworks interference checking function to check the optimized boom system to ensure through optimized boom system dose not exist interference and canmeet the design goals.The article makes a study of the finite element analysis of concrete pumptruck boom system and the optimization between each adjacent arm hinge pointsystem section, to further rationalize checking arm strength, design boom andluffing cylinder hinge point of the system to provide a reference.
