摘要: 通过进行不同压力条件下的压力试验，找到高压电绝缘子压接过程中声发射参数与抗拉强度的对应关系，研究了纤维断裂对判定结果的影响。引入压力参数，通过对多种不同压力工艺下的保压阶段的声发射信号的分析，找到了与压接质量明显相关的声发射参数的最佳判定条件。改进了以往通过声发射参数绘图，靠人眼看图做模糊判断的方法，为机器自动识别判定算法奠定了基础。

Abstract: In this paper, the relationship between acoustic emission parameters and tensile strength of bonding process is found through pressure tests under different pressure conditions, and the influence of fiber fracture on the judging results is also studied. Through the statistical analysis of the acoustic emission parameters corresponding to the different results of the tension test, the optimum conditions of determining the acoustic emission parameters, which are obviously related to the quality of the compression joint, are found through the different pressure processes in the pressure-holding stage, and the previous drawing of the acoustic emission parameters is improved. The fuzzy judgment method based on the human eye graph lays the foundation for the automatic recognition and decision algorithm of the machine.
