检查结构件疲劳寿命的传统方法,是在疲劳试验机上连续地进行一系列试验。该法频率为一分钟数百周、所需试验时间有时要数周。然而据报道,现在美国通用汽车公司研究室首次研究成功的电化学技术在几分钟之内能精确测定铝试样的疲劳寿
The traditional method of checking the fatigue life of structural parts is to continuously perform a series of tests on a fatigue tester. The method frequency of hundreds of weeks a minute, the required test time sometimes weeks. However, it is reported that now the first GM electrochemical research laboratory in the United States electrochemical technology within minutes to accurately measure the fatigue life of aluminum samples
