Targeting the demands of structure health monitoring in aviation field,the static load identification method of static load was proposed based on the location of extreme stain value at the constraint edge.Aluminum alloy plate and carbon fiber plate were selected as the aviation typical materials. Moreover,static load identification and monitoring system based on fiber Bragg grating sensor network and resistance strain gauge array was built up respectively.The result demonstrated good applicability to isotropic material and orthotropic material,and showed same results upon structure parameters change. Experimental results showed the error was less than 20 mm at the 1 200 mm×1 200 mm aluminum alloy plate and the error was less than 11 mm at the 540 mm×540 mm carbonfiber plate. This method was reasonable in the practical static load identification.
