Abstract

Considering the phenomenon of detonation wave breaking and incomplete cutting during cutting and separation by wire cutting, the influence of the air gap on the detonation transmission performance of a network cutting separation mechanism was studied. A specific lapping module of the cutting system was designed, and finite element modeling and dynamic simulation of the cutting process were conducted. The detonation transmission and cutting process on various working conditions were simulated. The critical air gap thickness of the cutting cable that can be detonated reliably and wherein the detonation wave propagates stably is between 2.30 mm and 2.35 mm. Combined with the simulation results, the up-and-down test was carried out, and various lap models with different air gap thicknesses were designed. The reliable critical air gap thickness is approximately 2.38 mm. The reliability calculation results on different air gap thicknesses are presented. These provide theoretical and experimental support for the lap structure design and reliability analysis of the linear separation system.
