Abstract: | AbstractCondition monitoring intervals are usually set at fixed intervals of length typically set by a mixture of British Standards, manufacturer's recommendations, and personal experience. These rather ad hoc methods have little scientific basis. A recently developed condition based maintenance model is described which utilises reliability data combined with condition monitoring measurements. This model provides the necessary basis to optimise condition monitoring intervals. Results obtained using artificial data, based on typical machines found in a hot strip mill, show how the model can be used as part of a condition based maintenance strategy. |
