The torsion spring is cylindrical in shape and has a torsion arm at its end for bearing a load, the torsion arm being fixed to the other components, and when the other components rotate around the center of the spring, the torsion spring pulls them back to the original position, generating a torque or rotational force. Torsion springs can store and release angular energy or statically hold a device by rotating a moment arm about a central axis. According to the requirements of users, the shape of the torsion spring is more, including no support lug, the included angle of the torsion arm is 90 degrees or 180 degrees or the torsion arm with the support lug, the torsion arm is parallel, and the like.
In order to verify the reliability of torsion spring parts applied in the fields of aerospace and aviation, loading fatigue tests are often required to be carried out on the torsion spring parts for several hours under a specific torsion angle, and whether the torsion spring parts generate plastic deformation due to material failure under a simulated working condition is verified. At present, in a related aerospace manufacturing plant, a torsion spring loading test device is used as process equipment in the production and processing process, and the torsion spring is used for reliability verification before being put into use, and the main defects of the torsion spring are as follows:
