ANSYS is used as the finite element computing platform to analysis a certain type of bus body frame under four load conditions of bending conditions, reversing conditions, the bending and torsion conditions and the emergency braking conditions. The constraints and load approach in the four conditions are given in this paper. A certain type of bus body skeleton program and the finite element analysis are conduct. The result shows that: (1) Bus body frame changing brings the re-distribution of the stress, making the overall stress and deformation of the body skeleton relatively uniform. (2) The improved program makes more than 250KG weight losing of the body frame and the changing location of the maximum deformation under the bending conditions. The maximum bending deform increased is only 8.92%.

Abstract. For analyzing the frame whether meets actual driving needs, LCK6105PHENV-type hybrid (electric and gas) city bus frame as research object, using Solidworks12 and ANSYS-Workbench14 on frame, respectively, for the three-dimensional modeling and finite element analysis. Static analysis obtains frame’s stress and deformation results under the condition of bending and reversing (wheels dangling), modal analysis gets frame’s front 6 order vibration type, inherent frequency and the maximum deformation. Analyzing results shows that the frame basically can meet the design requirements, and in line with the actual needs of living and production. This research will provide references for optimization and improvement of new-energy Auto frame.

Working Performance

Open-front press is one of the dominating equipment for punch forming. Body frame is the primary loadbearing part of this machine, and its rigidity and intensity have great influence on the working performance. In order to optimize the structure of body frame and shorten the product development cycle, finite element analysis, which is an effective technique in CAE, is used to investigate the body frame’s deformation and stress distribution in the presented work. By taking JC21-160, a representative type of open-front press, as the analysis object, the whole procedures of this work, such as modeling, meshing, loading, constraint handling and the solving, have been discussed explicitly. The analytical method and result will conduce to improve the structure design of this kind of machine and the similar devices.

Crucible frame structures are otherwise called as complex frame structures and its study is needed for further improvement in the emerging technology. The frame structure are frequently used an operational system support of  other mechanisms of a physical construction and/or steel frame that limits the assembly's extent in this study crucible frame structures are analysed using Finite element analysis and the results are expected in terms of safety for actual use. Based on ANSYS Software, the crucible structure can be meshed (discretized into several parts are called elements). At last, we can apply the boundary conditions and calculate its maximum deformation by applying various loads.

Biological Selection

The study obtains a methodology for the bionic design of the tower for wind turbines. To verify the rationality of the biological selection, the Analytic Hierarchy Procedure (AHP) is applied to calculate the similarity between the bamboo and the tower. Creatively, a bionic bamboo tower (BBT) is presented, which is equipped with four reinforcement ribs and five flanges. Further, finite element analysis is employed to comparatively investigate the performance of the BBT and the original tower (OT) in the static and dynamic. Through the investigation, it is suggested that the maximum deformation and maximum stress can be reduced by 5.93 and 13.75% of the BBT. Moreover, this approach results in 3% and 1.1% increase respectively in the First two natural frequencies and overall stability.

Linear Solution

A computational technique of rigid-plastic finite element method by using the Eulerian meshing method was developed to deal with large deformation problem in metal forming by replacing the conventional way of applying complicated remeshing schemes when using the Lagrange’s elements. During metal forming process, a workpiece normally undergoes large deformation and causes severe distortion of elements in finite element analysis. The distorted element may lead to instability in numerical calculation and divergence of non-linear solution in finite element analysis. With Eulerian elements, the initial elements are generated to fix into a specified analytical region with particles implanted as markers to form the body of a workpiece. The particles are allowed to flow between the elements after each deformation step to show the deforming pattern of material. Four types of cold forging and sheet metal clinching were conducted to investigate the effectiveness of the presented method. The proposed method is found to be effective by comparing the results on dimension of the final product, material flow behaviour and punch load versus stroke obtained from simulation and experiment.

Corrosion Defects

The failure assessment for corroded pipeline has been considered with the burst test and the finite element analysis. The burst tests were conducted on 762mm diameter, 17.5mm wall thickness and API 5L X65 pipe that contained specially manufactured rectangular corrosion defect. The failure pressures for corroded pipeline have been measured by burst testing and classified with respect to corrosion sizes and corroded regions — the body, the girth weld and the seam weld of pipe. Finite element analysis was carried out to derive failure criteria of corrosion defect within the body, the girth weld and the seam weld of the pipe. A series of finite element analyses were performed to obtain a limit load solution for corrosion defects on the basis of burst test. As a result, the criteria for failure assessment of corrosion defect within the body, the girth weld and the seam weld of API 5L X65 gas pipeline were proposed.
