In the arresting system of aircraft carrier, the condition of arresting cable is crucial for the safe recycling of aircrafts on the carrier. To effectively test the damages of cable and ensure the safe and reliable operation of the arresting system, damage detection testing is carried out for the cable. Firstly, a cable test platform is set up based on the magnetic flux leakage testing technology. Inductor element and Hall element are combined to make a ring array sensor and then the wire fracture defects and damage defects of sectional area are made to have testing through permanent magnet excitation. The testing results show that on the test platform, the sensor can effectively detect the damage defects made on the cable and it has good SNR and repeatability.Thus, this testing method can be taken as a method for the nondestructive testing of the arresting cable of aircraft carrier.
