Gantry bucket wheel stacker-reclaimer belongs to large complex steel structure. Once it is instability at the working time that will make a large accident. So we have to calculate its strength and stiffness. But its connection and the working condition are very complex. And the size of the model is so large which leads to debase the calculation efficiency. This paper use Pro/E software to create the model. And use Pro/Mechanical to make a finite element analysis. Through the properly simplified the model, we can increase the calculation efficiency. During the calculation result we find that the Pulley yoke, Rigid leg and Flexible leg appear big stress areas. We will give an optimization design for the irrational place and high stress areas. So that to improve the Gantry bucket wheel stacker-reclaimer on-site safety. And provide a certain reference for the subsequent design and improvement.

The finite element analysis of large air cooling tower was carried out using ABAQUS. On the basis of strength above,8 types of the axial force are analyzed and summarized, find valuable rules, and put forward the further optimization design. So that it can satisfy the strength and stability of air cooling tower, the structure is more reasonable, reduce weight, reduce the cost.

Purpose The purpose of this paper is to realize the lightweight of connecting rod and meet the requirements of low energy consumption and vibration. Based on the structural design of the original connecting rod, the finite element analysis was conducted to reduce the weight and increase the natural frequencies, so as to reduce materials consumption and improve the energy efficiency of internal combustion engine. Design/methodology/approach The finite element analysis, structural optimization design and topology optimization of the connecting rod are applied. Efficient hybrid method is deployed: static and modal analysis; and structure re-design of the connecting rod based on topology optimization. Findings After the optimization of the connecting rod, the weight is reduced from 1.7907 to 1.4875 kg, with a reduction of 16.93%. The maximum equivalent stress of the optimized connecting rod is 183.97 MPa and that of the original structure is 217.18 MPa, with the reduction of 15.62%. The first, second and third natural frequencies of the optimized connecting rod are increased by 8.89%, 8.85% and 11.09%, respectively. Through the finite element analysis and based on the lightweight, the maximum equivalent stress is reduced and the low-order natural frequency is increased. Originality/value This paper presents an optimization method on the connecting rod structure. Based on the statics and modal analysis of the connecting rod and combined with the topology optimization, the size of the connecting rod is improved, and the static and dynamic characteristics of the optimized connecting rod are improved.

Drilling frame on TD165CH Down-The-Hole Drill that has large slenderness ratio and be longer than 10m is one component of Down-The-Hole drill which is mainly subjected to load.In the process of drilling, drilling frame is not only subjected to loads which are like tensile, compression and torsion and so on, and be under the influence of impacting and vibration of impactor,the situation of force is complicated.By analysing of working condition of Down-The-Hole drill,there get all kinds of limit states of typical working conditions, and then using Ansys doing finite element analysis, there get distribution of the stress and strain of drilling frame and the result of modal analysis to check whether drilling frame meets the requirements of strength and stiffness or not,and whether it is possible to resonate with the impactor or not.By analysis,Structure strength and stiffness of drilling Frame on TD165CH Down-The-Hole drill meet the requirements of practical engineering, and drilling Frame does not resonate with the impactor.

This paper has introduced the finite element analysis (FEA) into the ergonomic design to evaluate the human feelings numerically and objectively, and then into the optimization design of beverage containers considering human factors. In the design of the end of can (the lid of can), experiments and the FEA of indenting vertically the fingertip pulp by a probe and the tab of end have been done to observe force responses and to study feelings in the fingertip. A numerical simulation of finger lifting the tab for opening the can has also been performed, and discomfort in the fingertip has been evaluated numerically to present the finger-accessibility of the tab. The comparison of finger-accessibility between two kinds of tab ring shape designs showed that the tab that may have a larger contact area with the finger is better. In the design of beverage bottles served hot drinks, the FEA of tactile sensation of heat has been performed to evaluate numerically the touch feeling of the finger when holding the hot bottle. The numerical simulations of embossing process have also been performed to evaluate the formability of various rib-shape designs. The optimum design has then been done considering the hot touch feeling as well as the metal sheet formability.

The static and stability analysis of steel structure were taken according to steel structure work platform’s requirements and structural characteristics in a subway parking space by using the software model which is established by Pro/E software and implanted into the finite element analysis software ANSYS Workbench. The maximum deformation and stress in design load of the steel structure were calculated and the linear stress strength analysis of the key parts was carried out, also both the analysis and testing of the supporting pillar’s stability were performed. The results show that the structure model established by Pro/E and the calculation method are reasonable. Moreover, the calculation results are of high accuracy. The profile size is properly chosen and the structure bearing capacity and deformation meet the design requirements.

Due to the limitation conditions of computer hardware in the past, the structure members need to be simplified in order to save the computing resources during the finite element analysis (FEA). During FEA of Steel joints, the simplified model is considered as hinge joint, rigid joint or half-rigid joint, which is different with the actual force. With the improvement of computer technology and hardware, actual finite element analysis method (AFEA) is proposed in consider of influence of actual model, welding, plate size and bolts, which is a more acceptable method in Precision compared with last.
