METHOD AND SYSTEM FOR PERFORMING AND UTILISING LOAD MEASUREMENTS IN THE MAINTENANCE OF MACHINE COMPONENTS AND DEVICES RELATING TO PAPERMAKING

WIPO Patent Application WO2005100687

A3

The invention concerns a method and a system in the maintenance of machine components, devices and systems relating to papermaking, where the condition, state and/or performance of machine components, devices and systems relating to papermaking are monitored by monitoring systems, which are used for perform­ing load measurements and for collecting load measurement data comprising load measurement signals. In the method according to the invention, the measured load measurement data is processed in such a way that of the load measurement data one or more load characteristics are formed, which express the load directed at the machine component or device being measured. In the method according to the invention, load characteristics determined in real time are used as input informa­tion for an operational reliability model in order to provide an operational reliabil­ity model. The system according to the invention comprises means for processing the measured load measurement data in such a way that of the load measurement data one or more load characteristics are formed, which express the load level directed at the machine part, device, component or system being measured.
