Description

Technical Field

[0002] Vibration testing of products often requires the installation of fixtures to ensure that the sample meets the test specifications at fixed points. Typical vibration fixtures only need to provide a rigid connection between the test bench and the test piece.

Existing vibration fixtures can only lock the shaft of the angular displacement sensor after the rotor angle has been adjusted. For products with low static friction torque, the installation and locking process causes the rotor to rotate, making it impossible to control the rotor angle and thus compromising the accuracy and reliability of the test data. Furthermore, this method requires clamping for each angle, resulting in poor flexibility and low efficiency. Summary of the Invention
