Belt–pulley systems are widely used in the industry due to their high efficiency and their low cost. However, only few works exist about the monitoring of their degradation. This paper details the impact of belt looseness on electrical measurements under steady and transient state in order to identify spectral signatures. This analysis enlightens the advantage of the transient state to detect belt...
Belt-pulley systems are widespread in the industry due to their high efficiency and their low cost. However, there are only few works about the monitoring of their degradation. This paper deals with belt looseness detection. It presents an innovative method based on the application of a square-wave speed reference in order to monitor belt looseness. A statistical-based indicator is computed from the...
This article introduces an original and generic monitoring protocol suitable to build robust references for the diagnosis of mechanical drives. In a general way, an efficient diagnosis scheme is related to the ability of properly separate healthy and faulty operations. However, during healthy working, the level of a fault indicator may significantly vary with the load characteristics or the system's...
