Description

Technical Field

[0001] This utility model relates to the technical field of buffer testing equipment, and in particular to a buffer temperature and pressure acquisition and analysis system. Background Technology

[0002] The airborne buffers used in the aircraft delivery device differ from existing buffers on the market, such as spring buffers, rubber buffers, polyurethane buffers, hydraulic buffers, composite buffers, putty buffers, and elastic damping body buffers. They require small size, light weight, and staged damping characteristics. The initial acceleration of the mechanism platform must be close to free-fall acceleration, and after load release, rapid and smooth buffering must be achieved, resulting in a zero velocity at the end of the mechanism platform. The product's operating conditions, environmental requirements, testing procedures, and test records are conducted in accordance with aviation product standards; therefore, it is necessary to simulate the low-temperature environment at high altitudes, including the buffer itself and its connecting mechanisms.

[0003] Therefore, this application provides a buffer temperature and pressure acquisition and analysis system to meet the requirements. Utility Model Content

[0006] The buffer is installed inside the box via an installation assembly. The telescopic end of the buffer passes through the box and is exposed to the outside. The inside of the box is connected to external refrigeration equipment via a duct.

[0007] The buffer solution inside the buffer is connected to an analyzer via a connecting tube. The analyzer is located outside the housing and is equipped with sensors to detect the pressure and temperature of the buffer solution. After the buffer has been verified by the prototype structure, various low-temperature buffer solutions are injected into it to conduct low-temperature tests in multiple temperature ranges (multi-frequency step tests from -55℃ to 0℃). The test data are recorded in detail and the buffer solution with the best performance is selected for use by the buffer.

[0008] Preferably, the analyzer is further provided with a constant voltage DC power supply, a data acquisition card and a data storage device. The constant voltage DC power supply powers the sensor and the data acquisition card. A resistor is connected in parallel on the path between the sensor and the data acquisition card. The data acquisition card stores the acquired information in the data storage device through data conversion.

[0009] Preferably, both the box body and the box lid have a double layer, and the double layer contains insulation cotton.

[0010] Preferably, the mounting assembly includes a support base and a slide base. The slide base is located at the bottom of the housing to support the buffer. The slide base is slidably connected to the bottom of the housing via a drive mechanism to clamp the buffer. By setting up the mounting assembly, the buffer can be quickly installed and fixed. In conjunction with the air duct, the temperature inside the housing can be reduced to simulate scenarios under different ambient temperatures and to test the performance of the buffer solution.

[0011] Preferably, the driving mechanism includes a screw and a handwheel, the screw is rotatably connected to the slide, and one end of the screw passes through the housing and is connected to the handwheel. The housing has a threaded hole that meshes with the screw.

The test data are recorded in detail and the buffer solution with the best performance is selected for use by the buffer.

[0014] In this invention, the buffer can be quickly installed and fixed by setting up the installation components, and in conjunction with the air duct, the temperature inside the chamber can be reduced to simulate scenarios under different ambient temperatures, thereby testing the performance of the buffer solution.
