PROBLEM TO BE SOLVED: To solve the problem in which, when load conditions and boundary conditions at the time of stress analysis are different from conditions in an actual operation state, life prediction is hard to be performed with high accuracy.SOLUTION: Detection results are input from a plurality of sensors for detecting an operation state of a loading shovel, to an input device. A processing device analyzes the detection results of the sensors which are input through the input device by using an analysis model, thereby calculating stress applied to parts of the loading shovel. The processing device calculates a temporal change of the stress applied to the parts of the loading shovel from a temporal change of the detection results of the plurality of sensors and obtains the life of the parts on the basis of the calculation result of the temporal change of the stress. |
