Supporting Apparatus of Two-Dimensional Section Model in Wind Tunnel Test having Magnet Damping Structure and Wind Tunnel Testing Apparatus having such Supporting Apparatus

摘要

The present invention relates to ″a support device of a model test specimen for a wind tunnel test, having a non-contact type magnetic damping structure, and a wind tunnel test device provided with the same″, in which a non-contact type magnetic damping structure for the adjustment of a damping ratio is provided and precise adjustment of a damping ratio can be carried out very easily in the non-contact type magnetic damping structure when carrying out a wind tunnel test for a model test specimen having a reduced test target structure such as bridge upper structure. In the present invention, provided is a support device of a model test specimen for a wind tunnel test, comprising upper and lower horizontal frames (12a, 12b), a model coupling frame (13) and an elastic member (3), wherein the model coupling frame (13) has a magnetic member (2) for generating magnetic force, and a conduction plate mounting frame (10) is provided and has a conduction plate (11) facing the magnetic member (2) in a non-contact state such that non-contact type magnetic damping acts by the magnetic force between the magnetic member (2) and the conduction plate (11), thereby resulting in damping of the vibration of the model coupling frame (13) due to the vibration of the model test specimen (120). In addition, provided is a wind tunnel test device provided with the same.
