摘要
Abstract
AS the layer of glass fabric increases,the fold is more likely to be produced in the manufacturing process of blade girder.Due to the existence of fold,the fatigue performance of blade becomes worse and the operation life will be drastically declined.By designing different types of fold system and manufacturing different samples,the influence of different fold ratio,different fold offset angle and fold width ratio on the fatigue performance of blade girder was studied in detail in this article.The results show that the fatigue performance of GFRP declined sharply with the increase of ratio between height and width of the fold.And no obvious difference was found in the fatigue performance when the samples with different angular offset were tested under the conditions of same fold.Within the certain range of ratio between fold width,the fatigue performance declined slowly.But,when it is above the certain range,the performance began to drop sharply.关键词
