摘要

Tower-wire model is established by use of ANSYS/LS-DYNA under the background of a long-distance transmission project. The dynamic responses are numerically simulated in the condition of transmission lines icing. Results show that impact effections of transmission towers on broken-line span and non-broken-line span nearly induced by icing and broken wires are both prominent. Stresses and displacements responses are distinct in boken-line span,and responses weaken gradually with the distance increasing from broken-point. It provides a reference for dynamic analysis of transmission tower-line system.
