【摘要】 简要介绍磁粉探伤-橡胶铸型法系统,通过试验,对检测孔内疲劳裂纹确定一条对应一定置信水平1-=95％的检测概率曲线,测得长度≥0.44mm的孔内疲劳裂纹,在95％的置信水平下有90％的检测概率。更多还原

【Abstract】 A magnetic testing-rubber cast inspection system is described. Corresponding to a given confi-dence level 1-α= 95%,probability curve for detecting inside hole fatigue cracks was settled by experiment. Fa-tigue cracks with length a≥0. 44mm was detected out. The detection probability is 90% at the confidence level of95%.更多还原
