Line Coupling

A nonlinear finite element model of transmission tower-line coupling system including transmissions, towers and insulators is established based on ANSYS in this paper. Based on the second development at the ANSYS computing platform, finite element model of a Tower-Line Coupling system was established. The approach is applied to study intial shape of Tower-Line Coupling System. With the comparison with classical test cases, the approach was validated, performing high computing efficiency.

Buckling Instability

One collapse tower of 110 kV transmission line was taken as an example and a finite element model for the coupled tower-line system was established for investigating the effects of the strong wind on the transmission tower and line. The result shows that the selected standard of material of some rod members is lower, and the area of their section is relatively small. Main legs present buckling instability because of being in compression under action of the strong wind, which leads to the collapse accident of the towers.

Abstract A finite element model was developed to simulate the tire-rim interface. Elastomers were modeled by nonlinear incompressible elements, whereas plies were simulated by cord-rubber composite elements. Gap elements were used to simulate the opening between tire and rim at zero inflation pressure. This opening closed when the inflation pressure was increased gradually. The predicted distribution of contact pressure at the tire-rim interface agreed very well with the available experimental measurements. Several variations of the tire-rim interference fit were analyzed.

Torsional Analysis

Abstract A three-dimensional (3D) beam finite element model was developed to investigate the torsional stiffness of a twisted steel-reinforced cord-rubber belt structure. The present 3D beam element takes into account the coupled extension, bending, and twisting deformations characteristic of the complex behavior of cord-rubber composite structures. The extension-twisting coupling due to the twisted nature of the cords was also considered in the finite element model. The results of torsional stiffness obtained from the finite element analysis for twisted cords and the two-ply steel cord-rubber belt structure are compared to the experimental data and other alternate solutions available in the literature. The effects of cord orientation, anisotropy, and rubber core surrounding the twisted cords on the torsional stiffness properties are presented and discussed.
