| Abstract:In response to the common problems associated with traditional crankshaft detecting methods, such as low measurement accuracy and high error rate, the intelligent eddy current/magnetic memory detector was used to detect the external defects of a crankshaft, and the ultrasonic detector was used to detect the interior of parts. On this basis, the test data was transmitted to the life evaluation software for the life evaluation of the crankshaft before remanufacturing. The practical application shows that the detection and life evaluation method is effective. |
