摘要
建立超声应力检测与校准系统,分别利用该系统和X射线应力分析仪对Q235钢、685钢、45号钢、铝合金等试样进行残余应力检测,通过对比研究表明两种方法的应力检测值并不相同,但是应力趋势基本相同。利用超声法对焊缝、平板类零件、轴类零件、管类内壁、螺栓、涂覆层下、玻璃及陶瓷等的残余应力分布进行检测,取得较好的应用效果。
A system of ultrasonic stress testing and calibration was established,and respectively using the system and X-ray stress analyzer to detect the residual stress in specimen of Q235steel,685steel,45#steel,and aluminum alloy.The comparative study shows that the detected stress values of the two methods aredifferent,but the stress trend isalmost the same.Finally,through using ultrasonic method,we obtain satisfiedapplicationresulton the residual stress testing of weld joint,flat parts,shaft parts,the tube inner wall,bolt,coatingparts,glass and ceramiccomponent,and so on.
