Problems solved by technology

However, the entire detection method cannot detect the jet hole with a small inner hole diameter. At the same time, the internal shape of the jet hole is relatively complicated, and the detection method cannot extend into the jet hole for detection.
Chen Hao studied the formation mechanism of jet penetration, the depth and diameter information of the inner hole formed by penetration, and studi

Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingly.

Abstract

The invention provides a jet flow penetration inner hole morphology measurement method, which solves the penetration depth and the internal volume by measuring the internal morphology of a jet flow penetration target plate, and comprises the following specific steps: 1, constructing an inner hole morphology measurement device; secondly, the jet penetration target plate is placed on a horizontal workbench, and the position of the jet penetration target plate is adjusted; thirdly, the endoscope downwards stretches into an inner hole of the jet flow penetration target plate to complete morphology measurement; and 4, solving the penetration depth and the internal volume of the jet penetration target plate.

Description

technical field [0001] The invention relates to the field of jet penetration test and testing, which is used for measuring the shape of a jet penetration of an inner hole, in particular to a method for measuring the shape of a jet penetration of an inner hole. Background technique [0002] At present, a lot of research has been done on the theoretical calculation and computer simulation of shaped jet at home and abroad, but the morphology of the inner hole formed by the jet penetrating the target plate has not been studied much, usually in the test of the shaped jet penetrating the target plate The dimensions of the perforations formed by the penetration of the jet are all measured after cutting the target plate. For the experiments that cannot directly cut the target plate and are inconvenient to cut the target plate, a method of measuring the inner hole shape extending into the injection hole is required, and obtaining real experimental data can be used to study the power ...
