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.

Terrorist attacks became a major threat to the safety, security, and economy of our nation in the last few years. The Attacks against important facilities could have different techniques; however the main source of ground attacks is the application of excessive amount of energy to the designated facility through a vehicle intrusion and/or a blast. In the current research, a new approach of using steel-structure barriers is presented. Several new structural anti-ramming barriers are designed and analyzed using nonlinear Finite Element Analysis (FEA). In this new design, commercial steel-structural components were used in order to reduce the manufacturing cost. These new steel-structure security devices have proven an excellent capability to sustain severe impacts by spreading substantial amount of the impact energy throughout the entire structure and the supporting soil/concrete. In the current research, three anti-ramming bollard systems, for K4, K8 and K12 impact conditions, were presented. The bollard systems were made of commercial steel unites connected together to produce the entire bollard structure. The FE modeling and simulation results of the bollard systems were presented in details in this paper. The FEA for the K4 bollard was validated by comparing the simulation results with the actual test results. The FE simulation results correlated very well with the actual test results. The steel-structure barriers could have much less shallow foundation to account for the in-city utility restrictions. It also has the advantage of easier and faster installation minimizing the required digging and installation time inside the city. The design could also be modified to account for different threat levels and different sites’ restrictions.

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.

Non-linear numerical simulation is done on A-type super high pier by using finite element analysis software ANSYS, obtaining the node stress distribution under load in the node area taken in the sequential layer analysis of overall mode. The conclusion is mainly as follows: the change of width and thickness of cross beam exerts slight impact on the maximum stress of the node while the change of cross beam depth impacts the node stress much. From the computation, it can be concluded that proper reduction of cross beam depth is beneficial to the node stress.

The Finite Element Analysis

Recently various types of sandwich panel are applied for constructing bridge and ship structures. Sandwich panel is material that consists of lightweight core material and two metal faceplates. The application of sandwich panel in ship structures makes the structure less-complex and ship’s selfweight lighter because of the reduction of secondary stiffeners. This paper discusses sandwich panel that was fabricated using synthetic resin core material and two steel faceplates. This study is aimed to analyze stresses developed in the sandwich panel of 750 GT Ro-Ro ship car deck structure when it was subjected to the deck design load. The finite element analysis was carried out to obtain the stress distribution and maximum deformation on the car deck structures. The stress of the ship car deck constructed using conventional steel structure, i.e. steel plate and stiffener, was compared with the stress of the deck that was built using sandwich panel.

In order to verify whether the inputting cantilever of bucket-wheel reclaimer will be cracked and plastic deformation, in this paper, with inputting cantilever of modeling and finite element analysis, 3D entity model of inputting cantilever is established by using CATIA software. With the transmitting data interface of ANSYS software, it imports the inputting cantilever model, which is established in the environment CATIA, into ANSYS software. Through the static analysis on the inputting cantilever by the finite element software ANSYS, we can get static deformation diagram and von stress distributing diagram. From the analysis results, we can find the weakest spot according to the displacement cloud chart, and find the stress most centralized spot according to the stress analysis cloud chart, then carry on the intensity examination to it, and make description and mark on the maximum deformation and the maximum stress spot, and put forward the improvement plan to improve the service life. This method is a efficient path for the design and intensity examination of inputting cantilever, and it provides theoretical basis for further optimization design.
