From the parametric modeling, the APDL tool can be used in ANSYS to build the finite element model of rhombic wire wound vessel. Only a small amount of parameters have to be input in order to accomplish the whole process of program development such as constructing model, meshing, creating contact pairs, bringing restrictions and loads to bear on vessels as well as solving and post-processing. It can be easy to use the developed batch program to achieve the finite element analysis of vessels and get the influence of interbedded friction on the load capacity of rhombic wire wound vessel under different working pressures.

To research the load upper bracket of Francis hydroelectric unit, then established the finite-element model, and analyzed the structure stress of 7 operating condition points with the ANSYS software. By the strain rosette test, acquired the data of stress-strain in the area of stress concentration of the upper bracket. The inaccuracy was considered below 5% by analyzing the contradistinction between the finite-element analysis and the test, and match the engineering precision and the test was reliable. The finite-element method could be used to judge the stress of the upper bracket, and it could provide reference for the Structural optimization and improvement too.

The natural rubber compound of each layer of solid tire had determined the mechanical properties in tension. It was found that the stress-strain relation of each material tire layer was fitted very well with the Ogden constitutive model. The R2 which was 0.986, 0.996 and 0.985 represented the certain curve fitting on the internal, middle and tread layer of solid tire, respectively. Subsequently, the Ogden model was implemented in the finite element model of the rubber specimen and solid tire. The finite element analysis results obtained an average error of 18.00% and 14.63% for the specimen and solid tire model by comparing to the physical experiment, respectively. Particularly, the mechanical properties of the natural compounds could be used to predict the ultimate compression load for the solid tire failure.

In this paper, the clamping unit of a two-platen injection molding machine was modeled by Pro/ENGINEER, and was imported to Altair HyperWorks. In HyperMesh module, the finite element model was set up, ANSYS has been used in the finite element analysis of the clamping unit and the deformation and stress results were obtained. Based on the topology optimization of HyperWorks/OptiStruct, recommendations to improve the structure of the clamping mechanism are presented; the results showed that less material was used while its performance was maintained.

The finite element model about greenhouse canopy of seismic analysis was setted up, The finite element analysis software ANSYS was used to study structure displacement, stress analysis on greenhouse shed. The results showed that the dangerous part of the canopy were located on upper chord members,lower chord members, web members of the framework and the lower and upper, the inside of both sides of the wall with seismic load.Corresponding to this results ,the main destroied form were the framework damage caused by the bending deformation of upper chord members, lower chord members and the upper web members and the unstability caused by the distortion of both sides of the wall.

This study proposes a new correlation improvement technique for the optimum node removal location to get improved modal assurance criterion (MAC) matrix. The technique is applied to updating of the finite element model (FEM) of a structure. The developed routine is tried on a utility helicopter. It is proven that it is capable of showing better performance than the coordinate MAC (coMAC), commonly used in such analyses. Commercial software is utilized for the finite element analysis of the helicopter fuselage and tail. Experimental modal analyses are also performed for updating the model for tail of the helicopter to demonstrate the effectiveness of the new technique.

In this paper, authors made contrast with the three finite element methods in analysis accuracy and usability .Those are all based on the structural analysis of mining excavator arm. The first fem is using UG solid modeling capabilities to create model .The finite element model is generated by UG_ANSYS, including setting the loads of material properties and boundary conditions ,also loading work. The process is called preprocessing completely .Then export a“. inp” file,after that, imported that file directly into ANSYS software for solving. The second one is to import solid mode created in UG into ANSYS software directly ,then take pretreatment and solution accordingly.The last one is using UG modeling and UG NX NASTRAN (the finite element analysis function) for structure analysis. It is concluded that using UG completely pretreatment of ANSYS analysis method and UG NX NASTRAN method feel more convenient to operate it with the high analyze accuracy,with the two methods , designers can modify mining mechanical arm weak positions more easily.In turns,they can improve the designing level of physical prototyping.

The weight control agency of crawler crane machine may be in the problem of inadequate strength in engineering applications. It will be analyzed and improved design by finite element. The bracket and frame are respectively calculated by static, established the finite element model, imposed loads, solved the result and sum up the stress distribution disciplinarian. The improved agencies are re-analyzed by the ANSYS. After re-analyzed, the intension of the weight control agency meets the strength requirement.

The model of the spindle was made while the related characteristics and parameters were analysising,and then it was inducted in ANSYS finite element analysis software. Through carrying the constraint on the finite element model, the spindle was completed to realize the finite element analysis. At last, the model was inducted in MATLAB to establish the optimal model, through the mathematical model ,it was realised to complete optimization analysis.
