Insect flying form observing and dynamic characteristic testing device

Abstract

The invention provides an insect flying form observing and dynamic characteristic testing device which comprises a base, an observing box, a stimulating module, a micro pulling force detecting module, an image collecting module and a controller. The observing box is arranged on the base and is used for placing of insects. The stimulating module is arranged on the side wall of the observing box and is used for stimulating the insects, and the insects are urged to fly or change the flying states of the insects. The micro pulling force detecting module is placed on the lower portion of the observing box and is used for computing the kinetic parameters during insect flying according to the displacement caused on the insects during insect flying. The image collecting module is used for collecting images of the flying states of the insects. The controller is arranged on the side face of the base and is connected with the stimulating module and the image collecting module respectively, and the controller is used for controlling the stimulating module and the image collecting module. According to the testing device, effective flying observing can be carried out on the insects, direct and accurate measuring can be carried out on the kinetic parameters during practical insect flying, accurate samples can be provided for insect flapping wing flying mechanism research, and meanwhile the device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of insect bionic experiment research, in particular to an insect flight form observation and dynamic characteristic testing device. Background technique [0002] At present, bionics, as a flourishing interdisciplinary subject, has gradually become a research hotspot at home and abroad. Among them, the flight mode of insects with variable configuration and flapping wings may give people a lot of enlightenment of great significance, thus bringing new ideas and new methods to the fields of advanced power propulsion systems and micro air vehicle design. However, the small size of insects makes it difficult to effectively guide and control their flight behavior. At the same time, due to the limitations of existing technology and instruments, it is also difficult to observe its complex flight state, measure and record tiny dynamic parameters. [0003] According to the investigation of domestic and foreign experi...

Problems solved by technology

[0004] However, the above three methods have the following disadvantages: Method 1 uses software to calculate the flow field and mechanical properties, and the values ​​of some variables are not yet clear, and there are large errors

Method 2 focuses on the observation of the flow field, but due to the inaccuracy of the flow field measurement itself and the complexity of the flow field, the calculation of the mechanical properties based on the flow field is relatively rough, and accurate results cannot be obtained

The model of method 3 cannot replicate all the characteristics of insect wings, and the law of motion must be simplified when driving the model's wings, otherwise it will exceed the range of motion that the existing mechanical structure can achieve, thus introducing some errors
