Digital testing method for penetration depth of energy-gathered jet flow of cutting rope

The invention discloses a digital test method for the penetration depth of energy-gathered jet flow of a cutting rope, and belongs to the field of initiating explosive device tests.The digital test method comprises the following steps that S1, a cutting rope assembly is bonded to the F face of a polycarbonate plate through an adhesive; s2, obtaining a penetration surface; the D face of the polycarbonate plate is clamped through the clamping tool, the cutting rope assembly is detonated through the end of the electric detonator, and after the cutting rope assembly works, a penetration trace is left in the polycarbonate plate; and S3, penetration depth measurement: placing the D surface of the polycarbonate plate on a horizontal working table of a measurement device, and focusing by a telecentric lens to obtain a complete penetration curve. The method has the beneficial effects that the polycarbonate plate with high light transmittance and high toughness is selected as the standard test target plate, a neat and
