Background
The eddy current dynamometer is generally applied to the durability fatigue test of an engine, and after the eddy current dynamometer is used for a certain time, the eddy current ring which is a main core component of the eddy current dynamometer cracks and leaks water in a ring body due to expansion with heat and contraction with cold, so that a coil is short-circuited, and the dynamometer needs to be disassembled and overhauled. In the conventional state evaluation of the vortex ring in maintenance, whether the ring body is cracked or not and leaks water is checked by naked eyes, but fine cracks are often difficult to find by the naked eye evaluation, and the cracked vortex ring can cause coil short circuit again in a short time after being used due to the water leakage of the vortex ring, so that the test efficiency is influenced, and unnecessary part loss is caused.
In addition, the dynamometer after maintenance cannot check the leakage of the whole system water channel, the leakage can be checked only on a test bench in the past, and once the leakage occurs, the dynamometer needs to be detached for maintenance. This process delays the test and increases the amount of work.
