METHOD FOR GENERATING A SIMPLIFIED CALCULATION MODEL AND METHOD FOR PREDICTING LIFE CONSUMPTION OF A COMPONENT

摘要

The present invention relates to a method for generating a simplified calculation model for use in predicting life consumption of a component subjected to loads during operation, comprising the steps of: receiving a first set of load input data resulting from a first set of load sessions during operation; calculating at least one of stresses, strains and temperatures for a critical area of said component by means of a numerical calculation model; predicting life consumption of said component based on said at least one of the numerically calculated stresses, strains and temperatures; and generating said simplified calculation model defining a relationship between load input data and predicted life consumption by means of: assigning a plurality of linear difference equations for said simplified calculation model; and calculating parameters of said plurality of linear difference equations based on said relationship between the first set of load input data and said numerically calculated predicted life consumption. The present invention also relates to a corresponding systems and computer program products thereof. Furthermore, the invention also relates to a method for predicting life consumption of a component and a corresponding system thereof.
