| Popis: | Overhead power transmission lines are subject to various static and dynamic loads. Among the dynamic loads treated quasi-statically in the line design process are imbalances due to the sudden fall of ice accreted on conductors and ground wires, a phenomenon known as ice-shedding. In order to study the static and dynamic effects of this physical phenomenon on towers as well as on phase-to-phase and phase-to-tower spacing, a series of laboratory tests were conducted on a two-span reduced-scale setup representing two level, equal conductor spans anchored at the end points and suspended in the middle by an insulator string. In these experiments, ice-shedding loads were simulated by suddenly dropping dead-weights from the conductors. Concurrently, a nonlinear finite-element model using ADINA was developed to simulate the static and transient dynamic responses of the physical model. This paper describes the essential characteristics of the numerical model and compares its predictions with the experimental results from a typical case. The comparison shows the good performance of ADINA in modelling the static and transient dynamic responses of this highly nonlinear engineering phenomenon. |
