Abstract

An apparatus for predicting a deterioration and damage in a structural member of a prime mover or the like has a use condition monitoring unit for monitoring a condition of use of the structural member, an inspection unit for inspecting a deteriorated and damaged state of the structural member, a use condition setting unit for setting a use condition by being supplied with use condition data of the structural member from the use condition monitoring unit, a simulation unit for forming a model of the deterioration and damage in the structural member on the basis of the use condition of the structural member and a result of inspection of the structural member at a preceding time, and for simulating the advancement of the deterioration and damage in the structural member on the basis of the deterioration/damage model, and an inverse analysis unit for correcting a simulation model formed by the simulation unit by comparing the simulation model with a result of inspection of the structural member at the present time. The simulation unit is arranged to predict a future deterioration and damage in the structural member by using the corrected simulation model and the result of present inspection. By a deterioration/damage prediction apparatus of the invention using this apparatus, the deterioration and damage in the structural member can be accurately predicted using a simulation and an inverse-problem analysis method with respect to use conditions and results of inspection of the structural member, i.e., information actually available.
