Abstract

The invention discloses a magneto-elastic cable tension measurement method and a reconfigurable magneto-elastic cable tension sensor thereof. The method comprises steps: a steel cable is magnetized; stress changes of the steel cable are monitored; and a real-time cable tension value of the steel cable is acquired. When the above method is used for monitoring the cable tension of the steel cable, one-time magnetization can be carried out on the steel cable, induction electrical signals are acquired in multiple directions, and thus, reliability of the monitored data can be improved. According to the reconfigurable magneto-elastic cable tension sensor, the main body unit comprises a shell, a first signal output joint, a second signal output joint, a signal input joint, a magnetic yoke, a positioning plate, an excitation wire and induction coils, wherein the excitation wire is wound on a groove body structure; the induction coils are arranged on the inner side surface of the positioning plate and arranged coaxially with the magnetic yoke; and the joint is connected with the coil. Two main body units are in butt joint. As the excitation coil and the induction coil do not need to be wound in the field, consistency of the wound coils can be ensured, measurement result accuracy is ensured, the work difficulty is reduced, and the workload is reduced.

Description

technical field [0001] The present invention relates to the technical field of cable force measurement, and more specifically, to a method for measuring magnetic cable force and a reconfigurable magnetic cable force sensor. Background technique [0002] Due to the outstanding advantages of high flexibility, high tensile strength, and long load transmission distance, steel cables have been widely used in fields such as long-span bridges, large-scale building structures, and traction machinery. Such as stay cables, wire ropes for passenger ropeways and elevators, and various lifting equipment slings, etc. During the service process of the steel cable, damage will accumulate due to the influence of atmospheric environment corrosion, mechanical friction or fatigue damage; at the same time, due to the uncertainty of the load, various damages will inevitably occur, resulting in a reduction in the actual load bearing capacity of the steel cable. The steel cable may break suddenly ...
