The invention relates to a mechanical product long-period fatigue test data processing and trend pre-judging method, which belongs to the field of aviation manufacturing. According to the method, on the basis of a three-layer mapping data structure, initial test data are classified and sorted, and generation of fatigue cracks is pre-judged on the basis of a trend judgment algorithm of statistics.Due to the fact that aircraft full-aircraft fatigue test data has the characteristics of being massive, disordered and the like, statistical analysis cannot be directly carried out on the test data, classification and sorting must be carried out according to the characteristics of the test data, and then fatigue test data trend pre-judgment can be carried out. By adopting the methods of test dataintegration, classification, trend judgment and the like, rapid sorting and classification can be effectively and rapidly carried out on the mass data of the full-aircraft long-period fatigue test ofthe aircraft, trend pre-judgment is carried out according to the integrated data, whether fatigue cracks occur in the structure or not is estimated, and reference is provided for testers.

    本发明涉及一种机械产品长周期疲劳试验数据处理与趋势预判的方法,属于航空制造领域。该方法以三层映射数据结构为基础,对初始试验数据进行分类排序,基于统计学的趋势判断算法进行预判疲劳裂纹的产生。由于飞机全机疲劳试验数据存在海量、乱序等特点,无法直接针对试验数据进行统计分析,必须先根据试验数据特点进行分类排序,然后才能进行疲劳试验数据趋势预判。本发明通过采用试验数据整合、分类及趋势判断等方法,能够有效、快速地针对飞机全机长周期疲劳试验海量数据进行快速排序分类,并根据整合后数据进行趋势预判,预估结构中是否出现疲劳裂纹,为试验人员提供参考。
