“…Niu et al [10] presented a general mathematical modeling approach for electric crane system dynamics during operation, which could be used to analyze the dynamic responses of electromagnetism, mechanism, and structure, during the operation of electric cranes. Wu et al [11][12][13][14] established a mathematical model of the horizontal and vertical vibrations of a crane structure under the trolley running and lifting processes by using finite element theory and calculated the vibration response of the main beam. The correctness of the theoretical solution was verified by experimental verification, and the parameters were modified.…”

The structural vibration of the main beam of a crane causes fatigue damage and discomfort to the driver. The swing of the payload has an effect on positioning precision, especially for a ladle crane, and this directly affects production safety. To study the influence of system parameters on the vibration of a crane's main beam and the angle of the payload, a system consisting of the main beam, trolley, payload, and cabin was constructed. A rigid-flexible coupling dynamic model of a moving trolley with a hanging payload that moves on the flexible main beam with a concentrated cabin mass is established, and the direct integration method is used to solve the nonlinear differential equations of system vibration, which are obtained through Lagrange's equation. Then, the time domain responses of the flexible main beam, payload angle, and cabin vibration are obtained. The influences of the trolley running speed, quality of the payload, and quality and position of the cabin on the vibration of the main beam and payload angle are analyzed. The results indicate that the amplitude of the main beam is directly proportional to the quality of the trolley, payload, and cab; the position of the cabin is closer to the mid-span; the amplitude of the main beam is larger; the structural damping has some influence on the vibration of the main beam; and the swing angle of the payload is related to the maximum running speed of the trolley, acceleration time, and length of the wire rope. In order to reduce the vibration of the main beam and cabin, the connection stiffness of the cabin should be ensured during installation.

Extruded aluminum profiles are widely used in building and automation structures due to their durability, lightweight, corrosion resistance, shorter fastening time and reusability. Proper design is crucial in maintaining the lifespan of these structures. It is therefore essential to determine the structural behaviors of the structures such as the natural frequency, mode shape, etc. The finite element analysis is a method which has been commonly used in determining structural behaviors. However, there are also numerous problems in analyzing these kinds of profiles using solid finite elements, such as modeling, meshing, solution time problems, etc. Therefore, beam finite elements have been used in the present study in modeling of the profiles. Furthermore, an equivalent beam element model has been developed for bolt-together connectors of the profiles. Simulation and experimental modal analysis have been conducted on example test systems. It has been demonstrated that this modeling technique is very practical and the results obtained from the method agree well with the experimental results.

“…FEM has eventually become an integral part or standard tool for design, synthesis and modeling process in virtually all-engineering sciences, such as, structures, thermodynamics, biomechanics, acoustics, materials, fracture mechanics, civil engineering, fault diagnosis and fluids dynamics etc (Borazjani, 2013;Bouaanani & Lu, 2009;Cheng, White, & Grosh, 2008;Dado & Shpli, 2003;Fiedler, Hosseini, Belova, Murch, & Öchsner, 2009;He & Kwan, 2001;Mackerle, 2004;Noack, Rolfes, & Tessmer, 2003;Smoljanović, Živaljić, & Nikolić, 2013;Tabiei & Wu, 2000;Wu, 2006;Zhang & Gay, 2007). However, during its application in different disciplines, preparations associated with discretizing intricate multidimensional geometries hinder its wide spread recognition as an analysis tool (Burkhart, Andrews, & Dunning, 2013;G.…”

An Adaptive Finite Element Analysis Integrated System supported through application of Case Based Reasoning (CBR) methodology is being proposed in this paper. The approach is fruitful for selection of an initial mesh from a library of solutions to initiate analysis process, as already tested optimal mesh will have lesser refinement iterations. The optimal mesh distribution, represented by object-oriented method, can be easily adapted to the topology of new problem in same domain. An integrated and universal structural analysis system models human reasoning by forming solutions through the retrieval and adaptation of successful strategies used in the past. Basic insight of two distinct subjects along with resolution of involved issues and integration strategy for development of an intelligent system is elaborated here. The research explains an algorithm for case retrieval and mesh generation procedures based on the principles of mapping method.
