Deformation and force self-sensing laminated rubber support based on fiber bragg grating
The invention provides a fiber bragg grating-based deformation and force self-sensing plate-type rubber support, which comprises a rubber support, a placing groove is formed in the side surface of the rubber support, and the placing groove is of an annular structure surrounding the circumferential direction of the rubber support and is in a wave shape; a fiber bragg grating is hermetically arranged in the placing groove, is arranged along the length direction of the placing groove, and surrounds the circumferential direction of the rubber support along with the placing groove; a plurality of upper measuring points, a plurality of lower measuring points and a plurality of middle measuring points are arranged on the fiber bragg grating at intervals, the upper measuring points are located on the wave-shaped upper wave crest of the placing groove, the lower measuring points are located on the wave-shaped lower wave crest of the placing groove, and the middle measuring points are located between the wave-shaped upper wave crest and the wave-shaped lower wave crest of the placing groove; the fiber bragg grating is connected with the demodulator, and the demodulator is wirelessly connected with the control terminal through the wireless terminal device. According to the plate-type rubber support, the vertical force borne by the plate-type rubber support can be monitored in real time, and whether the support deforms such as bumps or not can be monitored in real time.
本发明提供一种基于光纤光栅的变形和力自感知的板式橡胶支座，包括橡胶支座，橡胶支座的侧面开设有放置槽，放置槽为环绕在橡胶支座周向的环形结构，其呈波浪形状；放置槽内密封设置有一根光纤光栅，光纤光栅沿着放置槽的长度方向设置，其随着放置槽环绕在橡胶支座的周向；光纤光栅上间隔设置有若干上测点、若干下测点和若干中测点，上测点位于放置槽波浪形状的上波峰，下测点位于放置槽波浪形状的下波峰，中测点位于放置槽波浪形状的上下波峰之间；光纤光栅连接解调仪，解调仪通过无线终端设备无线连接控制终端。该板式橡胶支座既可实现实时监测板式橡胶支座承受的竖向力大小又可实现实时监测支座是否存在鼓包等变形情况。
