Electric arc wind tunnel temperature measurement conditioning module calibration connecting device and method

Abstract

The invention discloses an arc wind tunnel temperature measurement conditioning module calibration connection device and method, and the device comprises a box body, the interior of the box body comprises a common wiring module and a power module, and the front side of the box body is provided with an indicating lamp, a channel dial selection module, a rapid wiring module, a signal output module and a signal input module; the left side of the box body is provided with a multi-core cable module. The signal input module is used for receiving a first voltage value; the channel dial selection module is used for switching specific channels of the arc wind tunnel temperature measurement conditioning module; the multi-core cable module is used for receiving a second voltage value converted by the arc wind tunnel temperature measuring and conditioning module based on the first voltage value; the signal output module is used for receiving and outputting the second voltage value. The sub-modules connected with the arc wind tunnel temperature measuring and conditioning module are controlled through the channel dial selection module, and calibration of all the sub-modules of the arc wind tunnel temperature measuring and conditioning module is completed through one-time cable connection.

Description

technical field [0001] The invention relates to the technical field of high-temperature test equipment for aircraft materials, in particular to a calibration connection device and method for an arc wind tunnel temperature measurement and conditioning module. Background technique [0002] The arc wind tunnel is an effective and indispensable core experimental equipment to complete the design of heat-resistant structural materials for hypersonic vehicles. It can simulate the aerodynamic heating environment of various types of hypersonic vehicles within a certain range, and conduct aerothermal ground simulation for the experimental model. test. [0003] When the aerothermal simulation test is carried out on the model in the arc wind tunnel, in order to further understand the heat resistance and other characteristics of the material, it is necessary to monitor and accurately measure the temperature of the model in real time, and obtain accurate temperature data through the tempe...

Problems solved by technology

[0004] In the arc wind tunnel experiment, the measurement of temperature and heat flow is very important. However, the temperature measurement and conditioning modules currently in use usually have inaccurate zero points and accuracy of individual temperature measurement and conditioning modules during long-term use. Will affect the reliability of the experimental data

Modules with inaccurate zero points can only be discarded and placed, which is also a waste of resources to a certain extent
