On-Line Fault Diagnosis for Final Drive Based on Order Analysis

Abstract:

In recent years, a new technology is produced in automobile manufacture. It is to detect the quality problems for the fabrication of final drive on its production line. In order to study it this paper firstly analyzes the causes of failure about key components on final drive and introduces the principle and implementations of a on-line monitoring system based on order analysis. In contrast with traditional fault diagnosis methods, this method can solve the Frequency Blur Phenomenon when the turning speed changes. The experiments show that based on order analysis this system can identify typical faults of final drive, such as teeth-surface fault for driving gear, bending of main shaft, fault for driven gear, fault for bearing and so on. By detecting the change of energy of different order, the product quality can be controlled and the manufacturing technology can also be improved.
