Device and method of rigidity measurement of flapping wing ribs

Abstract

The present invention provides a device and method of rigidity measurement of flapping wing ribs. The device of rigidity measurement of the flapping wing ribs comprises a frame (1), a motor (2), a movement mechanism (3), a holding mechanism (4), a position sensor (5), a force transducer (6), a data collection card, a motor driver (7) and a master controller. The output ends of the position sensor (5) and the force transducer (6) are both connected with the input end of the data collection card. The output end of the data collection card and the motor driver (7) are both connected with the master controller. According to the device and method of rigidity measurement of flapping wing ribs, it is accurately measured whether the rigidity of each flapping wing rib is consistent or not, then the rigidity distribution of the flapping wings is controlled, and the left and right wings having the same force and moment character in the same flapping state are ensured, so that the manufacture precision of the flapping wings are improved, and finally, the maneuverability and the controllability of an ornithopter are improved. Moreover, the structure is simple, the cost is low, and the space usage is small, etc.

Description

technical field [0001] The invention belongs to the technical field of rib stiffness measurement, and in particular relates to a flapping wing rib stiffness measurement device and a stiffness measurement method. Background technique [0002] The flapping wing aircraft is a new type of aircraft that imitates the flight of birds or insects in nature. It has the characteristics of small size, light weight, high concealment and flexible use, so it has broad application prospects. Due to its unique advantages in micro-scale, the micro-orchid-wing aircraft has attracted more and more attention. [0003] Around this topic, although controllable flying flapping-wing aircrafts have been developed at home and abroad, there is still a big gap from the practicality. One of the main reasons is that in the production process of the flapping wing, it is impossible to precisely control the rigidity of the left and right corresponding ribs to be exactly the same, and finally the complete sy...

Problems solved by technology

[0005] However, in the traditional flapping wing manufacturing method, the selection of wing ribs is often based on experience. Therefore, it is impossible to ensure that the stiffness of the left and right corresponding ribs is exactly the same, and thus it is impossible to ensure that the left and right wings have the same stiffness distribution, which eventually leads to The left and right flapping wings produce different force and moment characteristics in the same flapping state, which affects the maneuverability and controllability of the flapping wing aircraft
