Selection Of

Finite element analysis has been done to analyze pump bearing assembly in interference assembly condition by ANSYS software. The press-in assembly environment has been simulated, and the maximum stress and maximum deformation of inner race have been analyzed. Studies show that with the increase of bearing size, the change law of maximum stress and maximum deformation does not single unidirectionally increase or decrease simply. At the same time, the interference value also influences the change law. So, in the bearing assembly tolerance selection the influence of the interference must be considered fully. The finite element analysis can guide the selection of fit tolerance.

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.

In order to reach the requirements of the newest generation of wire bonder, gas bearing positioning stage directly driven by voice coil actuators is designed.In the stage,an air decoupling mechanism is used. And the finite element analysis software ANSYS was used to analyze the static and dynamic characterizes of the stage so that the structure meets the requirement of stiffness,and at the same time,the moving parts are as light as possible. The simulated results show that the maximum deformation of work platform is in the work surface and the deformation is in request scope.,the deformation of decoupling mechanism is in the main driving rod contact, but this has a little influence on the stage.

In this paper, the sheet with hole for the finite element analysis, the location of maximum stress and maximum stress values are obtained under different load of edge of the hole, and the finite element analysis results compared with the classic Qi Erxi answers. This coincidence is not accidental, but it just shows their correctness. Therefore, we can use Qi Erxi answer when the calculation of the hole’s edge stress concentration and the condition of the force and the boundary are simple; while the it is complex, the finite element analysis can be used.

Automotive valve springs occupy substantial space in the cylinder head of an internal combustion engine. In this paper, the design and analyses of a flat spring concept, known as flexure bearing are presented. Further, design approach, characteristics and parametric characterizations of a single-piece flexure bearing concept are outlined. Finite element analysis was used in examining the flexure bearing strength for different designs, materials and thicknesses. The results show that the maximum stress values are independent of the material types when the number of arm is three and above. The strain values are limited to less than 1% for all materials when the thickness is more than 1mm.  The results have provided characteristics for future selection of the flexure bearing in relation to the intended axial displacement.

Aorta Injury

As many as 80% of patients with TAR die on the spot while out of those reaching a hospital, 30% would die within 24 hours. Thus, it is essential to better understand and prevent this injury. The exact mechanics of TAR are unknown. Although most researchers approve it as a common-sense deceleration injury, the exact detailed mechanism of TRA still remains unidentified. In this work, a deceleration mechanism of TAR was carried out using finite element analysis (FEA). The FE analysis aimed to predict internal kinematics of the aorta and assist to comprehend the mechanism of aorta injury. The model contains the heart, lungs, thoracic aorta vessel, and rib cage. High-resolution computerized tomography (HR CT scan) was used to provide pictures that were reconstructed by MIMICS software. ANSYS FE simulation was carried out to investigate the behavior of the aorta in the thoracic interior after deceleration occurred during a car crash. The finite element analysis indicated that maximum stress and strain applied to the aorta were from 5.4819e5 to 2.614e6 Pa and 0.21048 to 0.62676, respectively, in the Y-direction when the initial velocity increased from 10 to 25 m/s. Furthermore, in the X-direction when the velocity changed from 15 to 25 m/s, the stress and strain values increased from 5.17771e5 to 2.3128e6 and from 0.22445 to 0.618, respectively.
