Problems solved by technology

[0005] The technical problem to be solved by the present invention is that, in view of the problem that the sensor cannot be fixed by screws or directly bonded when measuring the vibration of the gun mount of a certain type of destroyer in active service, a kind of sensor, adapter screw, mounting seat and gun mount is provided. The vibration measurement installation structure of structural indirect bonding, including acceleration sensor, transfer screw, mounting base, insulating gasket and short signal line; Make sure that the axis of the acceleration sensor and the axis of the adapter screw are on the same line; the adapter screw is made of 45# steel, the external connection thread is used, and the upper end surface is square; the mounting seat is made of 45# steel, It is a cube, and there are threaded holes in the center of the 5 mounting surfaces of the cube, which are used to connect the adapter screws, and no threaded holes are opened on the bottom surface; the insulating gasket is made of polyimide board and has a square structure

Embodiment 1

[0023] Such as Figure 4 As shown, the sensor installation structure and the screw-fixed installation structure are used to install the acceleration sensor at the same position on the upper part of the 857-30mm ballistic gun mount, and measure the vibration acceleration parameters at this position when the 30mm ballistic gun is fired, and then compare the two installation methods The measured acceleration data were compared. Before the test, make preparations. First, use sandpaper to polish off the paint film and rust at the measuring point of the 30mm ballistic gun, and then drill M3 threaded holes at the measuring point. Wipe clean. Then install the sensor. The screw fixing method is to tightly fix the sensor on the surface of the measuring point through M3 screws. Wipe clean the surface and the front and back sides of the insulating gasket 4, and then tightly connect the adapter screw 2 to the threaded hole of the mounting base 3 according to the direction of the measured...

Embodiment 2

[0028] Adopt the sensor installation structure of the present invention to measure the vibration parameters of the gun mount when the gun mount of a destroyer in active service is on the upper part of the gun mount, and its measuring point position is as follows: Figure 7shown. Before the test, the sensor assembly work is carried out, that is, the bottom surface of the acceleration sensor 1, the upper end surface of the adapter screw 2, the bonding surface of the mounting seat 3, and the front and back sides of the insulating gasket 4 are wiped clean with alcohol, and then according to the measured acceleration Connect the adapter screw 2 closely with the threaded hole of the mounting base 3 in the direction. Put the upper end of the adapter screw 2 facing up, and then apply an appropriate amount of AB glue on the upper end, and then tightly bond the bottom surface of the acceleration sensor 1 to the upper end of the adapter screw 2, and fine-tune the position of the accelera...

Abstract

The invention, which belongs to the technical field of gun vibration testing, discloses a mounting structure of a shipboard gun carriage vibration measuring sensor. The mounting structure is assembledby means of gluing. A sensor is connected with and adhered to a connecting screw on a mounting seat; the connecting screw is connected with the mounting seat by threads; the bottom of the mounting seat is bonded to an insulating gasket; and then the mounting seat with the insulating gasket is bonded to a measuring point position of a shipboard gun carriage structure. When a shipboard gun is shot,an acceleration sensor senses the vibration of the gun carriage and outputs a signal; a charge amplifier carries out conditioning on the signal and then transmits the processed signal to a data acquisition recorder; and acceleration-time curve is acquired and recorded. According to the invention, a problem of mounting of the sensor for vibration of the gun carriage structure in gun shooting is solved; the measurement data can accurately reflect the vibration change state of the gun carriage structure at the position of the measuring point; and thus the technical support is provided for improvement of the shipboard gun and ammunition development.

Description

[0001] The invention belongs to the technical field of artillery vibration testing, and mainly relates to a mounting structure for a vibration measurement sensor of a naval gun mount, which is suitable for the vibration test of the gun mount structure when the naval gun is fired. Background technique [0002] When the naval gun shoots ammunition, the overall vibration of the gun mount not only affects the shooting accuracy of the naval gun, but also has a great impact on the working reliability and service life of the naval gun system components. Therefore, the test of gun frame vibration has important guiding value for the design of naval gun structure and ammunition. [0003] At present, the most widely used method for testing the vibration of gun mounts is the electrical measurement method. It converts the vibration signal into an electrical signal through an acceleration sensor, and displays and records it after being amplified by a signal conditioner. This test method has...
