| 摘 要： | 将模糊数学方法用于疲劳损伤计算，构造出了用于损伤计算的４种典型的隶属函数，对疲劳累积损伤法则进行了修正完善。通过对两个程序加载试验实例的计算对比，得出了比较满意的结果和规律，只要合理构造、选择隶属函数，会使寿命估算的准确度大大提高。

| Abstract: | By applying fuzzy mathematics method in the calculation of fatigue damage,four model subordinate functions are constructed and the rule of fatigue accumulating damageis modified. By compairing the calculation results with experimental results of two program-ming loading test.some satisfactory results and laws are obtained. By reasonable construct-ing and choosing subordinate functions,the accuracy of the predicted fatigue life can be in-creased greatly. |
