中文摘要:
      残余应力是消除外力或不均匀的温度场等作用后仍留在物体内的自相平衡的内应力,对构件的力学性能有显著影响,会引起零件发生翘曲或扭曲变形,甚至开裂,定量测量残余应力数值对改变构件疲劳寿命,预防构件发生脆性破坏具有重要意义。国内外对残余应力测量进行了深入的研究,提出了多种测试方法。详细介绍了有损及无损残余应力测量技术的测量原理及国内外目前研究现状,分析总结了影响测试精度的主要因素及改进方法;调研了目前市场上较先进的仪器设备及其供应厂家;针对盲孔法孔周围塑形变形及钻孔偏心、压痕法塑性区域半径、X射线衍射法试样内部显微组织结构、中子法零点漂移、超声波法测量尺寸带来的误差的重要改进技术;并对残余应力测量技术发展方向进行了展望。
英文摘要:
      Residual stress is an internal stress, which remains existing after eliminating the external force or uneven temperature field and other effects. This residual stress has a significant effect on the mechanical properties of the components, which can cause the warp, distortion, or even cracking in parts. Quantitative measurement of the residual stress is of great significance to change the fatigue life and prevent the brittle failure of the components. A variety of test methods of residual stress measurement. This paper introduces the principle and the research progress of destructive and nondestructive testing methods. The accuracy influencing factors and the improvement in measuring instruments are also investigated. The advanced instruments and their suppliers are surveyed on the market. Aiming at an improvement for the deformation of the blind hole and the borehole eccentricity, plastic area radius, internal microstructure, zero drift, measurement, the improved methods are put forward and the prospect of stress testing technology is also discussed.
