Method for model based vibration diagnostic monitor of rotating machines by judging machine condition being related to current function and previously established reference operating parameters

摘要

A forward selection and a model formation are based on oscillating magnitudes recorded in each case currently and operating parameters and information on interpreting the rotating machine obtained from the current functional context. A judgement of the machine condition of the current functional is related to previously established reference operating parameters. A current copy of the model formed in the s transferred to an adaptive model forming unit (20). The latter keeps as input values fixed without changing over a given time which are described as a reference operating parameter (17).
