Embodiment 1

[0018] The specified direction of the gas generator is as figure 1 shown. The test directions required for each environmental test are shown in Table 1. It can be seen that the impact test direction requires X+, the vibration test direction requires Y and Z, and the acceleration test direction requires X±, Y±, Z±.

[0019] The tabletop of the environmental test equipment used is as follows: figure 2 shown. The holes on each table are threaded holes for the installation and fixing of the test device. During installation, the holes on the test device must correspond to the holes on the table of the test equipment.

[0020] Such as image 3 As shown, a gas generator environmental test clamping device includes: 1-base plate, 2-pressure ring, 3, fastening bolts, 4-gas generator. The nine-fire gas generator is fixed on the bottom plate 1 through the pressure ring 2, and the bottom plate 1 and the pressure ring 2 are connected through fastening bolts 3. The bottom plate 1 is ...

Abstract

The invention discloses an environmental test mounting device with gas generators. The environmental test mounting device comprises a bottom plate (1), pressing rings (2), fastening bolts (3) and thegas generators (4), the nine gas generator (4) are fixed to the bottom plate (1) through the pressing rings (2), the bottom plate (1) and the pressing rings (2) are connected through the fastening bolts (3), the bottom plate (1) is welded into a whole through a flat plate, a right-side plate, a lower-side plate and a reinforcing rib plate, and all connecting holes in the bottom plate (1) correspond to connecting holes in the table top of test equipment. In the test process, the gas generators (4) and the bottom plate (1) only need to be mounted and fastened once without repeated loading and unloading, and test requirements in all directions can be met through connection between the different hole positions in the bottom plate (1) and the test equipment. By adopting the environmental test mounting device, environmental test assessment of the gas generators in the mass production test process can be efficiently, quickly and safely carried out.

Description

technical field [0001] The invention belongs to the field of gas generator environmental tests, and relates to a gas generator environmental test clamping device, which is mainly applicable to the environmental test assessment items of a certain type of gas generator in the process of mass production and trial production. [0002] technical background [0003] A certain type of gas generator is used for precise guidance and control of aircraft. It is an energy output device and is widely used in the industry. At present, the trial production batch of the gas generator is relatively large, and the production process is relatively complicated, and the environmental test assessment is a relatively cumbersome and time-consuming process. As shown in Table 1, environmental tests include vibration tests, impact tests, and acceleration tests, and each test has different requirements for the test direction. However, vibration test equipment, impact test equipment, and acceleration te...
