The invention relates to a dynamic monitoring method of measurement data in fatigue test of an aircraft structure. The method is characterized by comprising the following steps: 1, performing static strain displacement; 2, building a basic data template for static strain displacement; 3, performing fatigue strain displacement measurement; 4, building a basic data template for fatigue strain displacement measurement; 5, performing formal fatigue test, and calculating and determining static error; and 6, performing formal fatigue test, and calculating and determining fatigue error. According tothe method, the used theoretical foundation is accurate; the performing steps are clear, simple, easy to control through a computer, and easy to perform; the construction idea is clear; and the problem that whether the fatigue test of the aircraft structure is performed normally is hard to determine can be solved. 本发明涉及种飞机结构疲劳试验测量数据的动态监控方法，其特征在于，包括以下步骤：步骤、进行静力应变位移测量；步骤二、建立静力应变位移测量基本数据模板；步骤三、进行疲劳应变位移测量；步骤四、建立疲劳应变位移测量基本数据模板
