STRESS MONITORING DURING THE OPERATION OF A COMPONENT

摘要

The invention relates to a method for determining an operating stress on a component during the operation of the component, characterized by the following method steps: a) recording measured values for predefined measurement variables during the operation of the component for at least n, where n ≥ 2, predefined operating modes which are different from one another, which measurement variables are not equal to the operating stress on the component to be determined; b) determining m effect operands W1 to Wm, where m ≥ 2 and m ≤ n, in a predefined dependence on the measured values for each of the n operating modes; c) recording a measured value of the operating stress after operation of the component for each of the n operating modes; d) setting up and solving an equation system having n equations such that m weighting factors a1 to am are obtained and are used to weight the m effect operands W1 to Wm, wherein a sum of the weighted effect operands for each operating mode is equal to the measured value of the operating stress recorded for the corresponding operating mode; e) providing a calculation rule for determining the operating stress during the operation of the component using the weighting factors obtained.
