doi:10.3969/j.issn.1000-1093.2019.10.021

Abstract

Abstract: In order to study the failure characteristics of high-lock bolts used in composite structures under dynamic combined loading, a special experimental support device is designed based on the high velocity hydraulic servo-testing machine, and a loading method of collision type is proposed. Failure tests of CFBL1001-6-6/ CFNT1003CY6 high-lock bolts were conducted under the conditions of 0.01 m/s, 0.10 m/s and 1.00 m/s loading speeds, and pure tensile, 30° tensile-shear coupling, 45° tensile-shear coupling, 60° tensile-shear coupling and pure shear state, and the parameters of failure equation were obtained by fitting the experimental results. The experimental results show that the failure parameters of high-lock bolts under dynamic combined loading can be effectively obtained by using the proposed experimental method, and the failure mode and failure load of high-lock bolts are affected greatly by the loading mode and less at the loading speed.The experimental results are good agreement with the predicted results of failure equation, which indicates that the failure characteristics of high-lock bolts can be well represented by the failure equation.
