To provide a technique capable of creating a proper behavior simulation model with a load applied onto a measured object taken into consideration.

In a behavior simulation model creating system 100, a component force measuring instrument 110 oscillates the measured object by a prescribed input wave, and detects the load and a displacement of the measured object under the oscillated condition. A computing part 130 finds a hexa-axial matrix operation expression as to a relation between the load and the displacement as the behavior simulation model, using a method of least squares, a neural network or the like, based on the load and the displacement of the measured object.
