An aeroelastic model of 1∶200 ratio of cooling tower was designed by using beamnet method, and then in Tongji university TJ3 wind tunnel, the dynamic response tests were carried out. It has been confirmed that vibration modes and aerodynamic parameters, windvibration factors and testing feasibility meet the requirement of wind tunnel tests, and the proposed method can avoid the shortages of traditional methods. The influence of interference effect was discussed with wind tunnel tests, and some important conclusions were drawn.
