The torsion testing machine of seat belt limit bar is mainly used to test and analyze the mechanical performance parameters such as torque and torsion angle of limit bar. When the force limit rod of the automobile seat belt is stressed to a certain extent, the force limit rod is deformed, so that the seat belt can be pulled out continuously, thereby realizing buffering and reducing the pressure of the seat belt on the passenger's chest. The force-limiting rod produced by the manufacturer needs to be tested by a torsion testing machine. The torsion testing machine has a clamp for clamping the force-limiting rod, and a torsion force is applied to one end of the force-limiting rod. Under the feedback of the sensor, the testing software has a powerful data processing function, which can test the corresponding torque under a certain torsion angle, and can also test the corresponding torsion angle under a certain torque, and automatically generate test curves, test conditions and tests such as torque-torsion angle, torque-rotation angle, torque-time and torsion angle-time. This machine can also be used for torque testing of other parts.
