Testing device and method for monitoring steel wire rope-friction pad dynamic micro-friction state

The invention discloses a testing device and a testing method for monitoring steel wire rope-friction pad dynamic micro-friction state. The testing device comprises a base frame, a loading system, a micro-slip system and a state monitoring system, wherein the loading system comprises a weight loading system, a hydraulic loading system and a steel wire rope; the micro-slip system comprises a support system, a drive system and a friction transmission system; the state monitoring system comprises a dynamic tension monitoring system, a pad stress measuring system, a friction force measuring system and a micro-slip monitoring system. By utilizing the testing device and the testing method, dynamic alternating tension can be applied to the steel wire rope and dynamic micro-friction can be applied between the steel wire rope and a friction pad simultaneously, and dynamic tension evolution of the steel wire ropes at both sides of the friction pad, micro-slip amplitudes of different sections of a contact arc of the steel wire rope and the friction pad, stress change of the friction pad near the contact zone of the steel wire rope and the friction pad and dynamic friction force between the steep wire rope and the friction pad can be measured in real time.
