Description

technical field

[0001] The invention relates to a torque testing device in a thermal vacuum environment Background technique

[0002] Aerospace equipment has extremely high performance requirements due to the particularity of its application in the outer space environment. In order to meet the design requirements, it is necessary to simulate the thermal vacuum environment of outer space on the ground, and test the performance and function of the DUT under vacuum and thermal cycle conditions. For example, in the thermal vacuum test that drives or loads the tested part to simulate the drive and load of the tested mechanism, not only a reasonable transmission device is required, but also real-time high-precision measurement equipment such as torque, rotation angle and rotational speed. Ability.

[0003] Due to the reduced reliability of sensors and power equipment in a thermal vacuum environment, the service life is shortened, and it is difficult to control during the test pr...
