Summary: | Wire rope is considered as one of the most important aspects in the industries. It is widely used in many industries such as port, vehicle production, construction work, and many more which requires lifting, transporting, loading process. It has numerous benefits, including high tensile strength, sTable and dependable operation, and a great capacity for dynamic load and overload. Due to continual loading and operating, wire ropes are susceptible to flaws and damages. Therefore, attempts have been made to investigate various techniques for spotting deterioration on wire ropes to increase its reliability and safety.
Some of the most widely used non-destructive testing (NDT) methods are the magnetic flux leakage (MFL) testing, eddy current testing (ECT), acoustic emission (AE), ultrasonic guided wave testing (UGWT). As for the defects of the wire ropes it is divided in to two types. Those are localized fault and loss of metallic area. Magnetic flux leakage and eddy current testing is based on an electromagnetic principle. In the other hand, acoustic emission and ultrasonic guided wave testing is based on combination of electromagnetic and vibration principle. All the method above is proven to be capable of detecting a numerous defect on a wire rope.
The prototype rig was able to detect the defect that occur on the wire rope and able to distinguish the differences in the size of the defect using the peak-to-peak value from the signal. However, it could not give a clear classification between two type damages and the width of the damage. Moreover, usage of filter could reduce the noise and hysteresis. |
