Abstract
Random vibration due to the turbulence of airflow is observed on a flexible wing model below its flutter speed at the wind tunnel experiments. This paper presents a mathematical technique to simulate this random response of the wing model. The data of created signal is utilized for developing the flutter prediction method since the characteristics of structural dynamics can be theoretically given.
