说明：  计算混凝土泵车臂架疲劳损伤时采集的应变数据中含有奇异值会对损伤结果产生较大影响， 而传统的3 准则的判定值为常系数，不适合泵车臂架应变信号的变化． 对此，结合泵车臂架应变信号的特点，提出了剔除奇异值的新方法
(Fatigue damage calculation when the boom concrete pump strain data collected will contain singular values ​ ​ greater impact damage results, and the traditional three criteria for determining the value of the constant coefficient, is not suitable for pump truck boom strain signal changes. This, combined with the pump arm strain signals, the proposed new method of removing the singular value)
