摘要
结合有限元分析方法和叶片振动试验方法,利用最少的试验设备,检测出叶片危险部位的相应数据,以提高疲劳试验的可靠性。通过理论计算和数学建模相结合的方法,确定叶片阴阳两面最大变形位置,使试验条件更符合叶片的实际工况。分析试验结果显示,被测叶片达到了设计标准的要求。
In order to find out data of dangerous parts by the least experiment equipment and to improve test reliability, we combine finite element method and blade vibration experimental method. Through theoretical caculation and mathemetic modeling, the maximum deformation part is determined in negative side and positive side. The results show that the tested blades could reach the requirements of blade in design standard.
