| 摘 要： | 用磁性探头测量了45~#钢制开口环在承受偏心载荷作用下的应力分布,与有机玻璃试样的光弹检测结果基本一致.本工作将探测到的感生电压积分,直接获得磁感强度峰值与待测应力的函数关系.实验证实,在较宽的应力范围内,二者有较好的线性关系,易于作应力标定。

| Abstract: | The stress distribution of steel ring with a gap under concentric loading is measured by means of magnetic probe.This stress distribution is agreement with that of photoelasticity.In this work,the peak value of magnetization dependence of stress can be obtained directly by integrating the inductive voltage of magnetic probe.The experimental results show that the linearity of above relation is very well with a wide stress range.The stress distribution could be calibrated easily. |
