Finite Element Simulation and Small Scale Model Experiment of Catenary Icing
摘要
Abstract
In order to provide theoretical foundation for on-line monitoring of catenary, the static response of ice-coated catenary was investigated. First, a six-span automatic tensioned simple catenary finite element model was built via ANSYS, the static response of ice-coated catenary was conducted with different ice thicknesses, sag variations and end anchorage displacements of contact and messenger wire with different ice thickness were obtained. Then a 1/50 scale model of six-span catenary was constructed based on the similarity theory. End anchorage displacements of contact and messenger wire with diverse ice thicknesses were achieved through small-scale model test. Comparison of the displacements between small-scale model test and finite element simulation validated the feasibility of small-scale model. The results were converted to real catenary, which were compared with simulation results of real catenary, confirmed the correctness of the small-scale model. This small-scale model offers a basis for further research of catenary characteristics.关键词
