The spacecraft magnetic torque device is an important part of the spacecraft attitude control system, which adjusts the attitude of the spacecraft by generating a magnetic field. In the space environment, the magnetic torquer will experience extreme high temperature, low temperature and vacuum and other environmental conditions. If its high-low temperature resistance performance is insufficient, it may cause its failure or unstable operation, thus affecting the attitude control and mission completion of the spacecraft.
The high-low Temperature Test Chamber plays an important role in the high-low temperature resistance test of the spacecraft magnetic torque device. It can simulate the high-low temperature changes of the magnetic torque device in different environments such as spacecraft launch, operation and recovery, and evaluate its performance and reliability. The following is the application and test procedures of the high-low Temperature Test Chamber in the high-low temperature resistance test of the spacecraft magnetic torque device.
application
The application of the high-low Temperature Test Chamber in the high-low temperature resistance test of the spacecraft magnetic torque device includes:
High-temperature test: The magnetic torquer is placed in a high-temperature environment to simulate a spacecraft entering an orbit with strong solar radiation and test its high-temperature resistance.
Low temperature test: place the magnetic torquer in a low temperature environment to simulate the extremely low temperature environment of the spacecraft in the cosmic vacuum, and test its low temperature resistance performance.
Temperature cycle test: The magnetic torquer is placed in a high-low temperature cycle environment to simulate the temperature change of the spacecraft in different environments and test its performance and reliability.
experiment procedure
The test steps of the high-low Temperature Test Chamber in the high-low temperature resistance test of the spacecraft magnetic torque device are as follows:
Put the magnetic torquer into the high-low Temperature Test Chamber. Before placing it, it is necessary to ensure that the magnetic torque device has removed residual heat or moisture, and take anti-static measures.
According to actual needs, set the test conditions of high temperature, low temperature or temperature cycle. These conditions include temperature range, rate of temperature change, soak time, etc.
Start the high-low Temperature Test Chamber according to the set conditions and start the test. During the test, the high-low Temperature Test Chamber will automatically control the temperature and perform high-low temperature cycles within the set temperature range.
During testing, the magnetic torquer needs to be monitored to ensure its performance in high-low temperature environments. The monitoring parameters include the output magnetic moment of the magnetic torque device, the direction of the magnetic field, and the current consumption.
When the test is complete, close the high-low Temperature Test Chamber and take out the test equipment. Data analysis and evaluation is then carried out.
