AbstractTo measure dynamic stability parameters of HOPE-X at the NAL 2 m Transonic Wind Tunnel, new type of forced oscillation pitch/yaw and roll apparatus was developed. The cams applied in the drive apparatus are relatively short longitudinally so as to cope with high load and high drive frequency when used in the transonic region. Also developed were new balances with beams of high stiffness for pitch/yaw and roll drive apparatus. Data acquisition system for accurate dynamic measurement and parameter identification software for dynamic stability properties are used to identify very small damping parameters. To validate new apparatus and identification procedure of damping parameters a series of wind tunnel tests were carried out with a standard dynamics model (SDM). Test results at NAL 2 m Transonic Wind Tunnel showed to closely agree with those by the standard dynamics model in other facilities.
