| Abstract: | Aiming at the flight dynamic performance test application for the flapping wing flying robot,a design method for force sensor with high sensitivity and miniature(full scale 50 N) is studied.A new photoelectric force sensor is designed based on infrared photodiode which has the characteristics of fast response,wide linear range,convenient installation,simple interface circuit and so on.The designed elastic body has been conducted for stress-strain finite element analysis,sensor prototype has been conducted for static performance test after being trial-manufactured.Test results show that the photoelectric force sensor designed and manufactured has higher comprehensive performance with nonlinearity less than 0.3%. |
