Embodiment 3

[0109] At present, when measuring the electromagnetic ejection speed, the traditional method is that each probe is not connected to each other, independently induces a magnetic field and generates an induced voltage signal, which is displayed on the oscilloscope respectively. Then manual post-processing is required, manually adjust the cursor knob on the oscilloscope panel to adjust the induction signal curves of the two channels to a suitable position, and read the time difference between the two zero-crossing points by adjusting the vertical axes of the two cursors , and based on the distance between the two probes, the projectile ejection velocity is calculated.

Abstract

The invention discloses a magnetic probe array device and an electromagnetic ejection velocity measurement device and method. The magnetic probe array device comprises a plurality of magnetic probes, bottom plates fixedly connected with the magnetic probes respectively, and a skeleton fixation strip. The bottom plates and the skeleton fixation strip are provided with probe positioning holes for connecting the bottom plates and the skeleton fixation strip through screws; the skeleton fixation strip is provided with probe location holes corresponding to the magnetic probes respectively; after the bottom plates are connected with the skeleton fixation strip, induction coils of the magnetic probes pass through the probe location holes correspondingly; and the skeleton fixation strip has fixation strip positioning holes for enabling the skeleton fixation strip to be fixedly arranged to an electromagnetic ejection device through screws. The magnetic probe array device solves the problem of low measurement precision due to unstable external installation of the magnetic probes on the electromagnetic ejection device, and thus measurement precision is improved; and during repeated disassembly and assembly, positions and angles of the magnetic probes can be identical to those in the last time when the magnetic probes are reinstalled, and thus consistency of velocity measurement is improved.

Description

technical field [0001] The invention relates to the technical field of measuring the velocity in a bore of electromagnetic thrusting, in particular to a magnetic probe array device, an electromagnetic thrusting velocity measuring device and a method. Background technique [0002] The measurement of the velocity and displacement of the projectile is one of the important test items of conventional weapons. The test of electromagnetic thrust velocity and displacement is mainly concentrated in the bore and exit. Different from the ballistic test in conventional weapons, its mechanical force can be combined in electromagnetic thrust The structure is designed to install various sensors for testing. [0003] In the electromagnetic ejection internal ballistic measurement, the B probe is a commonly used measurement sensor, also called a magnetic probe. The B probe can be used as a section device and installed in the electromagnetic ejection device. When the armature passes by, An in...
