The equipment consists of a host, a fixed wheel group, a sliding wheel group, an optical cable bracket, an optical cable clamp (Haval), an extensometer (axial), an electrical control system, a computer, a printer, etc.

The host is a horizontal electronic testing machine structure, and the moving beam is connected to the sliding wheel group. The host consists of a base, a moving beam, a beam, a guide light bar, a high-precision ball screw, a screw protection cover, a manual control box, a sensor and a limit protection device, etc.

The servo motor, a reducer, a synchronous belt, and a ball screw constitute the driving components. The transmission principle of the host is: the high-precision wide speed ratio range servo driver receives the electrical control signal, controls the high-precision wide speed regulation servo motor, drives the reducer (imported) to operate, and then drives the double ball screws to rotate synchronously through the synchronous toothed belt to drive the moving beam to move; the moving beam is connected to the sliding wheel group, the optical cable is wound between the sliding wheel group and the fixed wheel group, and the moving beam moves in the direction of the optical cable tension, driving the sliding wheel group to complete the experiment.
