ACQUISITION METHOD FOR AERODYNAMIC FORCE AND ACQUISITION SYSTEM FOR AERODYNAMIC FORCE

摘要

PROBLEM TO BE SOLVED: To provide an acquisition method for aerodynamic force and an acquisition system for aerodynamic force that can simulate a state, in which a test object is applied, with high precision.SOLUTION: An acquisition method for aerodynamic force includes the processes of: acquiring an air blow state displacement as a displacement of a test object when the test object is excited in an air blow state; acquiring a no-air state displacement as a displacement of the test object when the test object is excited in a no-air state; creating an excitation and displacement model for the test object; specifying parameters of the excitation and displacement model by comparing the no-air state displacement with the excitation and displacement model; computing excitation force to the test object for reproducing the air blow state displacement using the excitation and displacement model having the parameters specified; and acquiring aerodynamic force from the difference between the computed excitation force and actual excitation force to the test object.SELECTED DRAWING: Figure 2
