摘　　要：为满足xx型号动导试验要求 ,在 1 .2m风洞内建立了一套自由翻滚 /强迫振动装置 ,采用小型电磁离合器、凸轮机构和步进电机的组合 ,满足了模型在风洞启动和关车时的锁紧、0°～ 360°自由翻滚、按预定规律强迫振动、试验装置阻塞度限制等多项要求 ,能在小风洞内完成国外在大尺寸风洞开展的同类试验 ,解决了型号研制的急需。It's very necessary to set up a set of free-tumble/faced vibration device in 1.2m×1.2m wind tunnel for the need of dynamic derivative model test of the ×× project. The mechanism adopts the combination of small electric clutch,cam gearing and repeating motor to actualize the function of motion and fastness of the model when the wind tunnel start and close, free-tumble vibration from 0° to 360°,the forced vibration in term of scheduled law and the limits of blockage etc., which made similar experiments what used to be done in large size wind tunnel overseas be completed in small size wind tunnel,and solved the urgent problems in the research of ×× project.
