Advanced computational modelling for vibration mitigation in guyed towers

拟议的研究结合了麦吉尔大学在缆索结构动力分析的先进计算程序方面的专业知识，以及IREQ （Hydro quamesbec research Institute）在缆索振动测量方面的实验专业知识。目标是开发、验证和测试一种准确的建模程序，以研究考虑导体-塔-基础-土壤相互作用的柔性输电塔的动力响应。校准的数值模型将用于开发高压线路支架在严重的风和大气结冰载荷下的减振解决方案。Hydro qusamubec的短期需求是减轻拉杆钢丝的振动，这种振动会导致岩石锚杆疲劳，从而减少其使用寿命，可能导致过早和不可预测的失效。彻底

The proposed research combines the expertise of McGill University in advanced computational procedures for dynamic analysis of cable structures, with the experimental expertise of IREQ (Hydro Québec Research Institute) in cable vibration measurements. The goal is to develop, validate and test an accurate modeling procedure to study the dynamic response of flexible guyed transmission towers with due consideration of conductor-tower-foundation-soil interactions. Calibrated numerical models will serve to develop vibration mitigation solutions for high voltage line supports exposed to severe combined wind and atmospheric icing loads. Hydro Québec's short-term need is the mitigation of vibrations in guy wires which cause fatigue in rock anchor rods, thus reducing their useful life with potential premature and unpredictable failure.
