The invention provides mobile floor equipment for eliminating a boundary layer of a wind tunnel test section, and relates to the technical field of wind tunnel tests. The moving belt floor equipment for eliminating the boundary layer of the wind tunnel test section comprises a frame body, a driving roller and a driven roller which are connected to the two ends of the frame body, a tensioning roller on the side face of the frame body, a moving belt wound on the peripheral sides of the driving roller, the driven roller and the tensioning roller, and two tensioning deviation correcting mechanisms on the two sides of the frame body. The tensioning deviation correcting mechanism comprises a cam, a driven sliding block, a tensioning sliding block, a displacement sensor, a driven sliding rail, a tensioning sliding rail, a tensioning support, a tension sensor, a linear grating ruler and a tensioning motor. And the movable belt is attached to the peripheral sides of the driving roller, the driven roller and the tensioning roller again, so that the movable belt is corrected or tensioned, the phenomenon that the movable belt slips or deviates is prevented, and the safety and stability of floor equipment are improved.
本发明提供了一种用于消除风洞试验段边界层的移动带地板设备,涉及风洞试验技术领域,用于消除风洞试验段边界层的移动带地板设备包括架体、连接在架体两端的主动辊与从动辊、架体侧面的张紧辊、及绕设在主动辊、从动滑、张紧辊周侧的移动带,架体两侧的两个张紧纠偏机构,张紧纠偏机构包括凸轮、从动滑块、张紧滑块、位移传感器、从动滑轨、张紧滑轨、张紧支座、张力传感器、直线光栅尺及张紧电机,本发明可通过检测移动带的张紧程度与偏移量,驱动从动辊与张紧辊单侧移动或两侧同时移动,使移动带重新贴合在主动辊、从动辊及张紧辊周侧,使移动带纠偏或张紧,防止出现移动带打滑或偏移现象,提升地板设备的安全性与稳定性。
