The invention discloses a calibration device for a flexible beam test piece, a torsion bending moment calibration device comprises a support frame, a clamp, a bearing seat, a torsion bar, a torsion plate, a screw and a weight, and the clamp is installed at the top of the support frame and used for clamping the flexible beam test piece; the bearing seat is mounted on one side, away from the clamp, of the support frame through the lifting adjusting assembly; the torsion bar is mounted on the bearing seat through a bearing; the torsion-increasing disc is arranged at the extension end of the torsion-increasing rod, and the other end of the torsion-increasing rod is connected with one end part of the flexible beam test piece through a bolt; the screw is mounted on the circumferential surface of the torsion increasing disc; the weight is hung on the screw through a rope. The torsion bending moment calibration work of the waving deformation section and the torsion deformation section of the flexible beam can be completed, frequent angle adjustment is not needed, calibration data are accurate, the structure is stable, the test period is greatly shortened, and the time cost is reduced.
本发明公开了一种柔性梁试验件的标定装置,其中扭转弯矩标定装置包括支撑架、夹具、轴承座、加扭杆、加扭盘、螺钉和砝码,夹具安装在支撑架顶部用于装夹柔性梁试验件;轴承座通过升降调节组件安装在支撑架顶部远离夹具一侧;加扭杆通过轴承安装在轴承座上;加扭盘安装在加扭杆的延伸端,加扭杆另一端与柔性梁试验件一端部通过螺栓连接;螺钉安装在加扭盘的圆周面上;砝码通过绳子悬挂在螺钉上。本发明能够完成柔性梁挥舞变形段和扭转变形段的扭转弯矩标定工作,无需频繁调整角度,标定数据精准,结构稳固,大大缩减了试验周期,减少了时间成本。
