Abstract

The Blocked Force Method has been stated in this study. A discussion of some promising benefits of using this method in the context of condition monitoring (CM) for rotating machinery also has been described. The Blocked Force Method is an inverse method where measured vibration signals are sent back to a position nearer to the source of vibration utilizing pre-measured frequency response functions (FRFs). The blocked force is obtained as a result of the inverse calculation, which can be measured only indirectly. This procedure can lead to two important benefits for CM applications. Firstly, the blocked forces are exact to a particular source, while vibration signals in machine casings comprise excitation effects from all active components. Therefore, by re-deploying the signals back to blocked forces, it is probable to spread out the signals from different components. Traditional techniques of signal processing can be applied with a cleaner signal as an initial point. Secondly, based on specific assumptions, blocked forces are an inherent property of the vibration source. This means that they can provide valuable insight into the source of vibration and help identify potential faults or abnormalities. Overall, the Blocked Force Method offers a powerful approach to condition monitoring by extracting blocked forces and utilizing them for analysis and fault detection.
