Embodiment Construction

[0046] The measuring device for axial load of cylindrical explosive container under internal explosion is as follows:

[0047] An explosive 6 is placed in the center of the cylindrical shell 1 with wall thickness h, inner radius R and length L, and an electric probe 7 is pasted on the surface of the explosive 6. The two ends of the column shell 1 are installed in the plate head 4 with ring grooves. The two plate heads 4 are connected by the evenly distributed screw 2 and the nut 3. The screw 2 and the nut 3 are used to connect the plate head 4 and the column shell 1 The connection is fixed, and the strain gauge is pasted on the screw 2. The explosive 6 is detonated by the detonator 5, and the electric probe 7 on the surface of the explosive 6 can obtain the accurate time pulse waveform of the explosive 6 detonated on the oscilloscope 12 through the detonation velocity meter 8, so that the accurate time sequence of the explosive load acting in the cylinder 1 can be judged. The si...

Abstract

The invention provides a measuring device for the axial load of a column-shaped explosion container. The measuring device comprises a column shell, two flat plate end sockets, an explosive, an electric probe, screw rods, nuts, a strain gauge and a detonator, wherein the two flat plate end sockets are arranged on two ends of the column shell and provided with circular grooves, the explosive is placed on the center of the column shell, the electric probe adheres to the surface of the explosive, the screw rods and the nuts are used for fixedly connecting the two flat plate end sockets with the column shell, the strain gauge adheres to the screw rods, the detonator is used for detonating the explosive, the electric probe is connected with an oscilloscope through an explosion velocity instrument, and the strain gauge is connected with the oscilloscope through a strain instrument. According to the measuring device and the measuring method provided by the invention, scaling model examination can be performed on a large size column-shaped explosion container according to an explosion similarity law, so that the intensity designs of the end sockets and the screw rods are optimized, the experiment cost is low, and the practicability is high. The measuring device provided by the invention has an important significance for knowing the axial load of the column-shaped container under the action of internal explosion, and is simple in experiment principle and easy to operate.

Description

Technical field [0001] The invention belongs to the technical field of explosion mechanics, and relates to a measuring device and a measuring method for the axial load of a cylindrical explosive container under the action of an internal explosion. The device and method of the invention are applied to the measurement of the axial load of the cylindrical explosive container. Background technique [0002] Explosive containers are widely used in scientific research, industrial production, storage and transportation of dangerous goods, and anti-terrorism because of their ability to effectively seal explosive shock waves and explosive products. Because the cylindrical container can easily realize a larger internal space, is convenient to process, and has a relatively low cost, it has been widely used. [0003] A typical cylindrical explosion container is composed of a cylindrical main cylinder, an end head and a connection structure between the head and the main cylinder. The complex ref...
