The Difference

With the method of FEA (finite element analysis), the distribution of temperature field in sense organ at different arrangements of hot-resistances and different accelerations, were obtained by building the three-dimensional model of airflow acceleration sensor’s sense organ.The results are asfollows: When the acceleration is not same, the temperature field distribution near the wires is different; The difference of temperature of 2 symmetry detection thermistors ΔT has also changed. If not beyond the measurement range, The more close to the heat flow center,the greater temperature difference between the two hot-resistances,and the greater output of voltage.

Portal axle unit is a gearbox unit installed on every end axles of the vehicle. It is installed to the vehicle to give higher ground clearance to enable vehicle to go over large obstacle when driving in off-road conditions. Shafts must be exceptionally tough and lightweight to improve the overall performance of the portal axle unit. In this paper, the shaft is analyzed in three-dimensional model and the stress of the shaft model is analyzed using finite element analysis (FEA). The FEA result is compared with experimental results.

In this paper we describe the potentialities of a tool for the visualization of experimental results directly on a three-dimensional model. The case study concerns the visualization of the results of a dynamic finite element analysis (FEA/FEM) applied to the calculation of seismic risk on works belonging to the Italian infrastructural heritage, specifically bridges, viaducts and overpasses. The project is based on finite element analysis performed on an exemplary set of 8 structures located on the Italian territory, performed by means of the open-source software framework OpenSees, according to the guidelines indicated in the Technical Standards for Construction NTC08. The application created for this project is classifiable as a webGIS, since all data are georeferenced and visualized on a map through an application executed through a browser. The graphical interface displays the interested works on the map of the Italian territory and allows to select them by mouse click. Following the selection, a 3D rendering of the model of the work and the surrounding terrain is shown, in which the results of the analysis are represented using color gradients directly on the three-dimensional model. The necessary tools are present for the selection of the type of result and for the animation in real time of the response of the work to the seismic action. The 3D representation is freely navigable by the user thanks to intuitive tools of panning, rotation and zoom through mouse and keyboard. The application takes advantage of HTML5, CSS and Javascript to show graphical features such as Cartesian diagrams of accelerograms used in modal analysis.

Background: The goal of this study was to analyze the stress distribution on two types of extra-short dental implants with 5 mm of length: An internal hexagon (IH) and morse taper connection (MT). Methods: The three-dimensional model was composed of trabecular and cortical bone, a crown, an extra-short dental implant and their components. An axial load of 150 N was applied and another inclined 30° with the same magnitude. Results: Stress concentrations on the IH implant are observed in the region of the first threads for the screw. However, in the MT implant the highest stress occurs at the edges of the upper implant platform. Conclusions: In view of the results obtained in this study the two types of prosthetic fittings present a good stress distribution. The Morse taper connections presented better behavior than the internal in both loading configurations.

This paper presents a new method for the analysis of the crankshaft strength by using the softwares of solidworks, matlab and ansys. Using the powerful modeling function of solidworks, the three-dimensional model of crankshaft was established. Applying the techniques of numerical operation, graph display and GUI of matlab, the simulation calculations of kinematics, dynamics of crankshaft was carried out and the force and torque of crankshaft was obtained. Making full use of finite element analysis function of ansys, the modal analysis and strength analysis of crankshaft were made. The results show that it is valid to take the respective advantages of solidworks, matlab and ansys to establish a simple and effective approach for the analysis of the crankshaft strength, which supplies foundation for the optimization design and dynamic response of crankshaft.
