Abstract
The extensive application of carbon fiber composite materials has put forward higher demands on de-formation monitoring technology.The current commonly used non-contact/contact deformation monitoring technolo-gies are difficult to simultaneously meet the requirements of global deformation monitoring and real-time perform-ance.Based on the Ko theory,this paper combines the working principle of strain sensors to construct a continuous bending deformation inversion theoretical framework.Through the spatial circular arc interpolation method,a visual-ization curve reflecting the deformation characteristics is obtained.In combination with the application requirements of the deformation inversion theory,a multi-channel sensor is developed.The sensor integrates 7 sensing units and an integrated plug-in gold finger interface.Each individual sensing unit has sensing performance comparable to commercial strain gauges.The measurement of circular rings with different geometric dimensions using the multi-channel sensor proves that the curvature radius error of the sensing results is less than 2.5%.Finally,the deforma-tion inversion system is used to test the deformation states of the simulated wing trailing edge structure.The inversion results show a high degree of consistency with the actual deformation results.关键词
