Advanced computational modelling for vibration mitigation in guyed towers

这项拟议的研究结合了麦吉尔大学在拉索结构动力分析高级计算程序方面的专业知识，以及魁北克水电研究所在拉索振动测量方面的实验专业知识。其目的是开发、验证和测试一种精确的建模程序，以研究柔索输电铁塔的动力响应，同时充分考虑导线-铁塔-地基-土的相互作用。经过校准的数值模型将用于开发暴露在严重的风和大气结冰载荷下的高压线路支架的减振解决方案。魁北克水电公司的短期需求是缓解拉索的振动，这种振动会导致岩石锚杆疲劳，从而缩短其使用寿命，并可能过早和不可预测地失效。一次彻底的

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.
