| description | Abstract To study the numerical relationship between the pull-out force and indentation depth of aviation wire crimp terminal, the crimping process between electrical contacts and stranded conductors and the tensile process of crimping assembly were simulated by the explicit dynamic finite element method. Regarding the variation trend of the tension of the crimping assembly with the tensile displacement during the tensile process and the failure mode, the numerical results and the experimental results showed a high degree of fit, and the relative error of the pull-out force was only 2.6%, which verified the reliability of the established numerical model. This model obtained the pull-out force curve of the crimp terminal that changes with the indentation depth. The authors suggest selecting the interval where the pull-out force is not less than 95% of the peak value, and the depth is less than the corresponding value at the peak value as the best value range of the indentation depth. |
