METHOD AND APPARATUS FOR IDENTIFYING CHARACTERISTIC VALUE

摘要

A method and apparatus for identifying a characteristic value in which the models can be developed similarly to a product of a combination of individual parts and integrated into an entire model. A function model of a part is made based on the phase difference and the flow rate representative of the intensity and quantity of energy applied to the part, the steady inner characteristic value in the steady state of the function model is identified, and the transient inner characteristic value in the transient state of the function model is identified using the identified steady inner characteristic value. The function model having the characteristic value identified by such an identifying unit is built in a virtual tester as an virtual prototype, the inner characteristic value thereof is evaluated by providing operating conditions and environment conditions, test data on an actual machine associated with these operational conditions and environmental conditions is compared with the inner characteristic value, and the characteristic value is reidentified, as required, depending on the comparison results.
