The Finite Element Analysis

The space curve meshing wheel (SCMW) has been studied previously for small power transmission. To extend its application in conventional power transmission, the bending strength of the SCMW needs to be studied. In this paper, the tine's section of the SCMW is optimized, the mechanical model of the bending strength is deduced according to the equations for a couple of given contact curves of the SCMW, and the design formulas of the tines are newly deduced based on the equal bending strength principle. Finally, one design example of a SCMW with elliptical torus cross-section tines is provided. The result shows that the theoretical design attained from the presented formulas coincides with that from the finite element analysis. It dedicates that the SCMW possesses enough equal bending strength to be used to in conventional industrial gearing device design.

The conductor is an important part of the process of power transmission. Keep conductor to be normal operation is an important link of power transmission. In practice, Due to the influence of many weather environments, such as wind, temperature, rain and snow, the conductor often appear ice disaster, dance and other disasters; therefore, the anti-vibration technology of conductor is an urgent need to develop. This paper masters the performance of damper by carrying out a great deal of performance test analysis, such as self-damping, the power of damper, anti-vibration effect. At the same time, this paper understands the effect of spacer arrangement on the sub span oscillation, through the finite element analysis and lingo program of nonlinear programming, laying the foundation for studying anti-vibration technology for large cross-section conductor.

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

One of the problems in installing cableway is the estimation of the tension. The mechanical model of coastal shore-to-ship transmission cableway was analyzed with catenary algorithm, compared with the finite element analysis of ANSYS software. The result shows that the tension and its changing amplitude are both gradually decreasing with the increase of the deflection. And, if the deflection is determined, the tension is decreasing with the increase of cableway’s span. These analysis results and conclusions can give the basis to safe installation of the cableway.

Elastic Distortion

The untwist of rotating blades in turbomachines treated so far in the literatare simply as a pure elasticity problem is generalized and formulated rigorously as a problem of aeroelasticity by variational principles (VPs) and generalized VP (GVP). It takes into account not only the centrifugal force, but also the aeroelastic interaction between blades and the flow as well as the elastic distortion of the cross section shape of blades, assuming the material to be linearly elastic but nonisotropic. Thus, a new rigorous theoretical basis for the finite element analysis of blade untwist in turbomachine design is provided.

Rockburst is a common dynamic failure phenomenon in deep-buried underground construction process, which greatly threatened the safety of equipment and person. In the paper, combined with the engineering of Xinjiang Xiabandi hydraulic and the Russense’s rockburst criteria, the finite element analysis are employed to study the effect of advance dig-hole and softening of surrounding rock. The results of the study indicate that the two measures can effectively reduce the intensity of rockburst level in the construction of deep-buried tunnel.

In order to study the force capacity of the cross steel reinforced concrete special-shaped column in horizontal load, the finite element analysis software ABAQUS has been used. We adopt a horizontal direction displacement loading method to apply horizontal load, and its displacement is 20mm. We simulate the stress distribution of the six rates of steel bone and the six different cross section sizes of steel reinforced concrete special-shaped columns. According to the result, the load - displacement curve has been dropped, and we analyze the mechanical properties of cross steel reinforced concrete special-shaped column by the curve. The results show that the bearing capacity of cross steel reinforced concrete special-shaped column has improved with the increasing of rate of steel bone and the cross section size.

The criterions of parameter selection for a tuned frequency muffler are proposed. The experimental results show that the radius of a cylindrical perforated tube dissipative muffler meets the criterions. Based on the conclusion, through installing the rotatable circumferential separate plates, an actuator of the tuned frequency muffler is designed to realize automatic adjustment of the radius, which is available for two kinds of working conditions of acoustic attenuation and can both attain the optimal acoustic attenuation performance. Utilizing the finite element analysis and the experiment test, variation rules of transmission loss versus the muffler’s radius is further investigated. The results show that the variable-radius method used in the tuned frequency muffler can shift the frequency band of acoustic attenuation and optimize the acoustic attenuation performance, which expands the application fields of mufflers and has a great engineering value.
