摘要: 纤维增强复合材料是一种轻质、高强、耐腐蚀且绝缘的新型材料,近年来在电力与通信工程中备受青睐,单管塔是其典型的应用形式之一。其变形能力强、耐疲劳、易于运输和施工,在近海、高原及山区等地区优势显著。本文开展了复合材料通信杆塔的足尺动力性能试验(自由振动法),获得了不同规格的复合材料杆塔在自由振动下的动力响应,并计算得到其一阶自振频率、阻尼比以及一阶振型系数。在复合材料杆塔的设计方法中,一阶自振频率和阻尼比是计算结构承受风荷载的重要参数,本文的试验结果可为复合材料杆塔设计参数的取值提供技术参考。

Abstract: Fiber reinforced polymer (FRP) composites are a kind of novel material, characterized by lightweight, high strength, corrosion resistance and insulation. In recent years, they have gained significant popularity in electrical engineering and communication engineering. Single-tube poles represent a typical application form. With the advantages such as large deformability, fatigue resistance, good durability and ease of transportation and construction, FRP poles are particularly prominent in offshore, plateau, mountainous, and other regions. Full-scale free vibration tests for the dynamic performance were conducted on the FRP poles for communication engineering, and the dynamic responses under free vibration of the FRP poles with different specifications were obtained, and their first-order natural vibration frequency, damping ratio and the first-order shape coefficients were calculated. In the design method of the FRP poles for communication engineering, the first-order natural vibration frequency and damping ratio are crucial parameters for calculating the wind load they are subjected to. The test results of this paper provide technical references for determining the values of design parameters of the FRP poles for communication engineering.

Key words: fiber reinforced polymer (FRP), communication engineering, full-scale test, natural vibration frequency, damping ratio
