Abstract
The invention relates to a fin dynamic principle imitating swing device.The fin dynamic principle imitating swing device comprises a swing platform, an elastic rod a, an elastic rod b and a fixed guiding frame, wherein the lower ends of the elastic rod a and the elastic rod b penetrate through two holes of the fixed guiding frame respectively, the upper ends of the elastic rod a and the elastic rod b are fixed on the swing platform through set screws, and the fixed guiding frame is used for restricting the whole device and guiding the elastic rods.The fin dynamic principle imitating swing device is light, small in inertia and high in efficiency and flexible controllability and can be used for various mechanical structure design occasions flexibly.
Description
Technical field
The invention belongs to bionic field, in particular to the imitative fin power principle pendulous device of one.
Background technology
The exquisite structure of organism, motion principle and behavior etc., become the object that robotics has a mind to imitate. Especially possessed the ability of at a high speed navigation as the animal in ocean, the advantages such as their motion efficiency height, control property flexibly be strong simultaneously, are more and more subject to concern and the application of domestic and international bionics. And Chinese scholars is comparatively extensive to the propulsion mode application of fin in water, such as the machine fish of the likeness in form trout of Massachusetts Polytechnics research, BJ University of Aeronautics & Astronautics develop " robofish " machine fish. But the application of fin inside motion principle is immature so far.
Summary of the invention
It is an object of the invention to the analysis to fin motion principle and research, a kind of imitative fin power principle pendulous device of design.
For achieving the above object, the design of the present invention is as follows:
By the analysis of fin inside motion principle and research being found, when fin side Muscle contraction, another pleural muscle meat will be forced to stretch, and fin swings to Muscle contraction side, otherwise fin swings to another side. According to above-mentioned motion principle, this imitative fin power principle pendulous device by regulating the flexible amount of two elasticity bars, thus can control this device end and carry out left and right swing.
According to above-mentioned design, the present invention adopts following technical scheme:
A kind of imitative fin power principle pendulous device, comprises oscillating platform, elasticity bar a, elasticity bar b and fixed guide frame; The lower end of described elasticity bar a and elasticity bar b is through two holes of fixed guide frame, and upper end is separately fixed on oscillating platform by tightening screw. Wherein the effect of fixed guide frame is to retrain whole device, and plays the effect of guiding elasticity bar.
The principle of the present invention is: utilize the inner motion principle of fin, by telescopic resilience bar, makes elasticity bar stretch out the length difference of fixed guide frame, produces internal stress, thus the elasticity distortion that bends, produce to swing.
Compared with prior art, the positively effect of the present invention is:
Weight of the present invention is light, inertia is little, efficiency height, control property flexibly are strong, can design occasion for various physical construction flexibly.

Fig. 2 is a kind of imitative fin power principle pendulous device one-piece construction figure.
Fig. 3 is a kind of imitative fin power principle pendulous device integral right pendulum figure.
Fig. 4 is a kind of overall left swing figure of imitative fin power principle pendulous device.
Embodiment
Do to illustrate in detail to the preferred embodiments of the present invention below in conjunction with accompanying drawing:
See Fig. 1 and Fig. 2, by the analysis of fin inside motion principle and research being found, when fin side Muscle contraction, another pleural muscle meat will be forced to stretch, and fin swings to Muscle contraction side, otherwise fin swings to another side. According to above-mentioned principle, a kind of imitative fin power principle pendulous device, comprises oscillating platform 1, elasticity bar a2, elasticity bar b3 and fixed guide frame 4; The lower end of described elasticity bar a2 and elasticity bar b3 is through two holes of fixed guide frame 4, and upper end is separately fixed on oscillating platform 1 by tightening screw. Wherein fixed guide frame 4 effect is to retrain whole device, and plays the effect of guiding elasticity bar a2 and elasticity bar b3.
In this implementation column, see Fig. 3 and Fig. 4, pull elasticity bar b3, the amount making elasticity bar b3 stretch out fixed guide frame 4 upper end reduces, release elasticity bar a2 simultaneously, the amount making elasticity bar a2 stretch out fixed guide frame 4 upper end increases, and elasticity bar a2 and elasticity bar b3 will be made to the right to bend, and oscillating platform 1 swings to the right; Otherwise elasticity bar a2 and elasticity bar b3 bends to the left, and oscillating platform 1 swings to the left.
Claims (1)
