摘要
The present invention relates to an apparatus and a method for calculating a fatigue usage factor with respect to fatigue generated in the material of a mechanical device depending upon changes of an operation environment during operation of the mechanical device. A fatigue usage factor UOP.cyc,transient n, which is based on the operation-transient state n, is calculated by multiplying a fatigue usage factor based on a design-transient state UDSGN.cyc,transient n by the value of a characteristic fatigue usage factor F (k) as shown in the following equation:UOP.cyc,transient n=F(k)×UDSGN.cyc,transient n Since a characteristic fatigue usage factor curve devised in accordance the present invention uses the characteristic fatigue usage factor curve obtained on the basis of the operation-transient state when calculating a transient-based fatigue usage factor, it is possible to much more accurately calculate the fatigue usage factor with respect to any operation-transient state of the mechanical device compared with the prior art.
