Finite Element Analysis And Structural Optimization For The Container Bilateral Side Crane

With the international trade increasing competition, the modes of containerterminal cargo transport produce great changes, thus contributing to the expansion ofthe size of the container terminal. At the same time we need more and more containercranes, which lead to the development of the industry and pay more and moreattention to its performance of lifting and safety factors. In order to meet the needs ofthe container market, the domestic container crane manufacturers seize theopportunity to develop container crane industry.Nowadays the Finite Element Analysis method has been widely used in thedesign process of the crane industry, but the calculation for bilateral side containercrane is little, resulting in the existence of a significant security risk in the course ofusing bilateral side container crane. As the new products of container crane industry,the security performance and vehicle performance of the product will directly affectproduction costs and user costs. So whether it is from the customer’s point of view orfrom the manufacturer, structural analysis and design optimization of the bilateral sidecontainer cranes are imperative.The main contents of this paper come from the cooperation projects of XCMGTruck Crane Co. and Mechanical Science and Engineering college of Jilin University,the paper is as follows:First, this paper introduces the bilateral side container crane current domesticsituation and the development process, and also clarifies the background andsignificance of the research. According to current state of the bilateral side containercrane, the author analyzes the future development of bilateral side, and explains thetheoretical and practical significance of hanging on the finite element analysis of thecontainer bilateral side of the crane. The author also introduces the structure of the container crane and technical parameters and characteristics.Second, the author uses the HYPERMESH software to simplify the originalmodel which the partner provides, the main work is including deleting redundantstructure, simplifying geometric model, optimizing the mesh quality and creating thefinite element model. After the completion of the finite element model, the authoruses the ANSYS Parametric Design Language (APDL) to assembly finite elementmodel of the various components, and to apply the constraints and loads of the modelbased on the actual operating conditions. The author uses the DOS command tocalculate the finite element model and improves work efficiency.Then, the paper introduces the finite element static analysis of the containerbilateral side of the crane, and the results were analyzed to determine the model of thestress large area. Based on the calculation result, the cause of stress concentration isdetermined, and then these areas are optimized to improve large area for stress, suchas the contact area of the slider. Because of the slider structure and unreasonableposition causing the contact stress concentration area, so the structure of the sliderareas is optimized. After analyzing the results, it formulates the optimal design basingon the problem of stress in different regions, and recalculates the optimized model.With Comparing analysis of the results of the optimization model, the authordetermines the area of the model which is still in need of improvement, and alsodetermines the optimal solution effectiveness.Finally, according to the results of the development of finite element stresstesting program, application DH5908wireless test system for dynamic strain stresstest side crane boom, and then verify the finite element model to calculate the loadconstraints and the correctness of the calculation results.In this paper, the author uses the HYPERMESH and ANSYS software to processthe original model and calculation analysis, and also uses the APDL language toassemble and calculate the model. In this paper, a combination of two kinds ofsoftware is used to deal with practical problem, this method is also applicable to other construction crane equipment for the analysis of similar structure to provide somereference.
