Description

Technical Field

[0001] The invention belongs to the technical field of mechanical testing, and in particular relates to a micro-newton-level flying insect contact reaction force testing system with no interference in the testing process, which has the characteristics of no interference in the testing process, micro-newton-level force measurement accuracy, etc. Background Art

[0002] The force exerted by the contact surface on the insect motion system is called the contact reaction force, and its test is widely used in the field of mechanical bionics. Movement is the basis for animal reproduction, predation, and avoidance of natural enemies. Many animals, such as flies, mosquitoes, and water striders, have unique motion functional characteristics that enable them to complete complex motion behaviors. Force measurement systems are constantly being developed to test insect contact reaction forces. The force exerted on the interface by flying insects during landing / takeoff is also a contact reaction force. The test of this contact reaction force is crucial to studying its motion characteristics and will also facilitate the development of small flying robots. The test accuracy of this contact reaction force is at the micronewton level, and the test process cannot be interfered with by humans, otherwise the contact reaction force test data will be inaccurate.

[0003] Invention patent CN101380235A discloses a method for testing the contact reaction force of animal foot-surface and a system force measurement technology. The method uses 16 sensors to form a 2×8 sensor array to test the contact force of animals on the ground, wall and ceiling surfaces. The test system is mainly composed of an elastomer, a metal strain gauge, a plexiglass plate and a camera. The elastomer structure is in an inverted T shape, and waist-shaped holes are distributed on it to reduce the weight of the elastomer and avoid the influence of gravity on the force measurement results. A square hole with a length and width of 31 mm is set at the corresponding force gauge position on the plexiglass plate. The force measurement range of the sensor force gauge is 30 mm × 30 mm, but this technology is suitable for testing the contact reaction force of large reptiles. It cannot meet the test requirements for flying insects, and it cannot test the contact reaction force during takeoff / landing. Invention patent CN107340231A discloses a centrifugal micro-newton-level insect friction online real-time test system and test method. The test system includes a test platform and its auxiliary mechanism, a speed regulating motor and a speed controller, a video monitoring system and a base that can realize the fixed installation of various components. It adopts a ball screw and a stepper motor structure, which can accurately control the displacement of the high-speed video imaging system. The camera center of the video monitoring system coincides with the center of the test platform. The camera has an adjustable degree of freedom in the vertical direction and can adjust its vertical distance from the test platform in real time. It is used to accurately obtain the radius information when the test object leaves the platform, thereby calculating the maximum adhesion force generated by the test object on the material surface. However, the force measurement system is only used to test the maximum adhesion force of insects on the material surface, and cannot test the contact reaction force generated at the interface when flying insects land / take off. Invention patent CN105444940A proposes a method for measuring tiny forces. The invention uses a shadow extraction method to observe the shadow area produced by the contact between the legs of aquatic insects and the water surface to calculate the motion support force. Based on the shadow images of the aquatic insects paddling on the water surface, the three-dimensional model of the aquatic insect legs is reconstructed through the Archimedean principle and the corresponding motion support force is calculated. The force measurement technology involved in the invention has a test accuracy of micronewtons, but the test objects can only be aquatic insects and cannot be used to test the contact reaction force of flying insects during landing / takeoff.

[0004] In summary, the current contact reaction force test system based on the force sensor array, centrifugal motion principle, and image processing cannot meet the requirements of the contact reaction force test generated at the interface when flying insects land / take off in terms of force measurement accuracy and test object fixing platform. Therefore, it is necessary to develop a micro-newton level flying insect contact reaction force test system with no interference in the test process (no influence on the physiological activity of insects) and micro-newton level force measurement accuracy.

The test process of the flying insect contact reaction force is described as follows: First, the carbon fiber spring and its mobile control component 1, the test system base and its lighting component 2, the organic glass cover and its scale component 3, the high frame rate camera and its fixing component 4 are placed on the test system base 2-7. The horizontality of the test system base 2-7 is adjusted by leveling the anchor bolts 2-6 to ensure that the test system base 2-7 is absolutely horizontal, and then the carbon fiber spring 1-1 is fixedly installed on the fan-shaped base 1-2, and the matching of the organic glass cover mounting slot 2-5 and the organic glass cover 3-4 is checked; the LED lighting source 2-1 is turned on to increase the brightness inside the organic glass cover 3-4. An electrical signal is applied to the stepper motor 1-7 through the stepper motor controller, and the stepper motor 1-7 drives the ball screw 1-12 to rotate, the pitch of the ball screw 1-12 is 1.0 mm, and then drives the fan-shaped base fixed slider 1-9 to move horizontally, so that the carbon fiber spring 1-1 passes through the carbon fiber spring placement square hole 3-1 and enters the organic glass cover 3-4, so that the effective working length of the carbon fiber spring 1-1 in the organic glass cover 3-4 is 50.0 mm; record the distance information of the carbon fiber spring 1-1 relative to the carbon fiber spring vertical positioning scale 3-5 in the vertical direction at this time, and then adjust the distance of the center of the high frame rate camera 4-1 lens in the vertical direction based on the distance information and with reference to the high frame rate camera vertical positioning scale 3-7, so that the distance between the carbon fiber spring 1-1 and the center of the high frame rate camera 4-1 lens in the vertical direction is consistent. Open the square hole baffle 3-8 for releasing flying insects, release the flies into the organic glass cover 3-4, and then quickly close the square hole baffle 3-8 for releasing flying insects to prevent the flies from flying away from the organic glass cover 3-4. When the flying insect lands on the carbon fiber spring 1-1 or takes off from the carbon fiber spring 1-1 without interference (without affecting the physiological activity of the insect), the carbon fiber spring 1-1 will be deflected. At this time, the high-frame camera 4-1 records the entire process in high-definition video, converts the recorded video into a picture, and imports it into the registered software copyright "Bionic Prototype Micromorphology Structure Deflection Solution System (Registration No.: 2020SR0755088)"; then, the position data and deflection data are obtained through the position and deflection information reference scale 3-6, which are 41.05 mm and 7.76 mm respectively; the characteristic equation of the carbon fiber spring 1-1, that is, the position-deflection-force equation
