Динамічний аналіз та оцінка улаштування кабелю на мості під впливом тайфуну

Abstract

In this scientific work, the 220 kV XLPE cable (model: YJLW02−127/220) will be laid along a sea-crossing bridge KV-2500 mm2 ) as the research object, the electromagnetic-thermal-structural multi-physical field numerical model is established by using “Comsol” simulation software. Applying the obtained pulsating displacement as a load on the cable so as to obtain the dynamic response characteristics of the cable. Have been analyzed the combined impacts on cables system within the analysis of methods of construction mechanics, planning site selection, bridge cable planning and other comprehensive aspects. The specified model scientific studies are important and relevant for the theoretical studies of work of real bridge constructions.
