Put the finite element analysis of line tower coupling modeling to the collapse of a 110 kV line straight-line tower, study the effect of strong wind on transmission tower and wire. The results show that under the action of strong wind, the material specification selected by the part of the rods on the type of tower is lower, cross section is smaller, the principal material of tower will be instable and flexional under the compression, resulting in tower collapsed.

According to uncertainty of the design parameters for large span truss of installing wave-maker, in order to avoid the waste of materials,the truss is analyzed based on the finite element analysis software ANSYS to find out its weaknesses and various parts of the deformation. On the premise of ensuring the intensity and stiffness, the weight of the truss is reduced by adjusting its sizes and selecting different profiles, so as to achieve the optimization of the truss of installing wave-maker.

Abstract In this paper, the finite element analysis of circular wedge connections is described, and conclusions for the performance of the connection are derived. In the foreground of the examinations are stresses and deformations while tightening of the connection. Starting with the general structural performance, the influences on power transmission like slope, number of wedges, coefficient of sliding friction and outer hub diameter are discussed. An analytic function to describe the gap pressure within the tightened joint is introduced and rates to explain the problem of centering of circular wedge connections are shown. Finally two concepts for dimensioning are presented and recommendations for application of this connection are given.

The Finite Element Analysis

In the traditional designs of milling cutter, we cannot get the required accuracy of machining as there may be local deformation on the edges, even more the cutter can break down. Aiming at this situation, a finite-element model of straight pin milling cutter with helical tooth are built using Marc, a nonlinear finite-element analysis software, the different cutting forces of the milling cutter during the cutting process are analyzed and the cutting forces of the milling cutter at different parameters are studied. We get the stress, the strain and the temperature distribution of the milling cutter in different situation. Our work offer a theoretical basis of improving stress of the cutter, designing the structure of cutters reasonably and analyzing the cutter failure as well as a new method of analysis and calculation of the cutter life and strength.

Based on the requirements of that the finger can move in parallel, and the displacement of the finger can be detected, the micro-gripper driven by piezoelectric actuator is designed based on the displacement amplification structure with the flexure hinge. The static analysis, the modal analysis, the harmonic response analysis and the transient response analysis of the micro-gripper are carried out by using the finite element analysis software ANSYS. The results of the finite element analysis show that the finger is fully able to move in parallel, and can detect the displacement of the finger; the maximum displacement of the finger is about 101 μm, the first natural frequency is about 130 Hz; the finger tip displacement under the 1 μm step input is about 20 μm, the fingertip vibration is about ±2 μm.

The numerical simulation calculation on round steel-tubes reinforced with CFRP sheets was done through the large-scale finite element software ANSYS. In this research, four factors were comparatively analyzed so as to obtain the influence of them on ultimate axial tensile bearing capacity of steel-tubes. These four factors are longitudinal reinforcement length rate , thickness , elastic modulus and circumferential reinforcement ways of CFRP sheets. The results show that the ultimate axial tensile bearing capacity of steel-tubes strengthened with CFRP sheets is enhanced significantly and the reinforcement effect is very good.
