Fluttering wing rib stiffness measurement device and stiffness measurement method

Abstract

The invention provides a flapping wing rib stiffness measuring device and a stiffness measuring method. The flapping wing rib stiffness measuring device includes a frame (1), a motor (2), a moving mechanism (3), a holding mechanism (4), and a position sensor (5), force sensor (6), data acquisition card, motor driver (7) and total controller; The output end of described position sensor (5) and described force sensor (6) is all connected to described data acquisition card The input terminal of the data acquisition card; the output terminal of the data acquisition card and the motor driver (7) are all connected to the general controller. The advantages are: (1) It can accurately measure whether the stiffness of each flapping wing rib is consistent, and then the stiffness distribution of the flapping wing can be controlled to ensure that the left and right wings have the same force and moment characteristics under the same flapping state, and improve the flapping performance. The manufacturing precision of the moving wing ultimately improves the manoeuvrability and controllability of the orthopter. (2) It also has the advantages of simple structure, low cost, and small occupied space.

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
