Fuse irradiation rig and control system thereof

Abstract

The invention discloses a fuse irradiation rig and a control system thereof, belonging to the technical field of fuse irradiation test. The fuse irradiation rig specifically comprises a base, a bracket and a transmission case, wherein a rotating ring of which the diameter is 170 millimeters is arranged in the transmission case; a sleeve is arranged in the rotating ring; the rotating ring passes through the transmission case; a support plate is fixed on one side of the rotating ring; the transmission case is connected with the bracket through a pitching driving mechanism and a self-rotating driving mechanism which are arranged on two side faces of the transmission case; the bracket is fixed to a revolving disk; the base is connected with the revolving disk through a horizontal rotation driving mechanism; and a distance adjusting mechanism is arranged in the base. The fuse irradiation rig is used for carrying out electromagnetic irradiation test on a large-caliber fuse (below 160 millimeters), and full-automatic accurate control over the fuse orientation, pitching, distance and self-rotation is realized through the control system, so that the influence of the rig on an electromagnetic irradiation field is reduced as much as possible.

Description

technical field [0001] The invention relates to an electromagnetic radiation test device and a control system thereof, belonging to the technical field of fuze radiation tests. Background technique [0002] During the flight simulation test, the test equipment is required to simulate the flight state of the fuze and wireless electronic equipment in various motion postures, and its azimuth and pitch angles are required to change at any time, and the electronic equipment and fuze are in a high-speed rotation state. At the same time, as the distance changes, the distance between the electronic equipment and the radiation source is getting closer and closer. Therefore, the radiation test of radio electronic equipment should be based on the attitude of the fuze in flight, and it is required that the test simulator can effectively simulate its real state. [0003] At present, the relevant tests on the radiation effect of electronic equipment are generally carried out by fixed pla...

AI Technical Summary

Problems solved by technology

[0006] (1) All changes in the direction and angle of electronic equipment require manual adjustment. Not only is it difficult to achieve precise direction and angle control, but also the test needs to be stopped for each adjustment, which increases the human workload. At the same time, because the equipment is completely driven by mechanical friction, adjustment It is quite laborious to install related parts;

[0007] (2) The rotation direction of the electronic device's elastic shaft can only achieve a small translation, which cannot meet the requirements for the 360° rotation of the test body in the test;

[0008] (3) The entire bottom is made of metal materials, although there is a certain distance from the test body, it still has a great impact on the entire electromagnetic field environment;

[0009] (4) The adjustment of the distance between the entire test platform and the radiation source needs to be manually pushed. Since the distance needs to be adjusted many times during the test, the workload is huge, and the adjustment accuracy of the distance under the condition of manual push cannot be guaranteed;

[0010] (5) The test platform can reliably clamp the test body with a diameter of less than 120mm, and the electronic equipment under test generally belongs to medium and large diameters (below 160mm), so this test platform cannot meet the test requirements;

This method can be used for electronic equipment, but it is not practical for other equipment under test

This also limits the scope of promotion and application of the test platform

[0012] Regarding the fuze electromagnetic radiation test bench, the applicant previously applied for a utility model patent, which is a multi-degree-of-freedom fully automatic fuze electromagnetic radiation test bench. The adjustment of the azimuth, pitch, distance, and rotation of the cylinder is imprecise, and it is difficult to achieve precise adjustment in a certain direction even with automatic control.

In addition, the adjustment of the device in the distance direction is completed by propulsion through the universal wheels at the bottom of the trolley with handles. This propulsion method has no guidance, and it is difficult to achieve the direction consistency between the test body and the radiation source during the test, which affects the test body. Nearby irradiance value measurement accuracy

The above-mentioned test device can only adjust one action within a certain period of time. Each action is related and cannot be crossed. It cannot realize multiple actions at the same time, which will affect the adjustment efficiency and thus affect the test progress.
