In order to explore the key influencing factors of explosion transmission capacity at the nodes of explosive cutting networks,flat plate detonation tests were conducted by changing the detonation gap between the cutting cord and the detonation column,and the test results were combined with simulation analysis to determine the simulation material parameters of the JO-11C detonation column.And the effect of detonation angle on the detonation capability was further analyzed.The results indicate that with the increase of detonation gap,the detonation capability decreases,the maximum detonation gap interval for the cutting cord to the detonation column is 2.0~2.5 mm;Meanwhile,increasing the detonation angle can significantly enhance the detonation capability.This research provides reference for the study of detonation transmission performance in explosive cutting networks and the improvement of weapon system reliability.
