Embodiment
Referring to Fig. 1-Fig. 6, the combined type resonance test demonstrating instrument of the present embodiment, including single pendulum module 2, spring leaf mode of resonance Block 1 and tuning fork resonance module 3, the single pendulum module 2, spring leaf resonance module 1 and tuning fork resonance module 3 are respectively positioned at three sections On slide rail, the slide rail and the slide opened up on bottom plate 5 are spacing;Outer-cover type casing 7 is also set with bottom plate 5, forms one The portable demonstration box of body formula.Positioned between bottom plate 5 and outer-cover type casing 7 by linking up with, or pass through positioning hole and supporting bolt It is fixedly connected, unscrews bolt during use.The outer-cover type casing 7 is provided with handle 7-1, is easy to carry.In this implementation, Flexible compact and resonance effect is have chosen in demonstration box significantly to test, by a series of improvement by abbreviation be suitable body Type.
Referring to Fig. 2, the bottom plate 5 is rectangle, and the first chute that section is in inverted T-shaped is set respectively along three sides of bottom plate 5 5-1, the second chute 5-2 and the 3rd chute 5-3;The section of the slide rail is T-shaped, as shown in figure 1, being resonated including retaining spring piece First slide rail 6-1 of module 1, the second slide rail 6-2 of positioning single pendulum module 2 and positioning tuning fork resonance module 3 the 3rd slide rail 6-3, slides spacing in corresponding chute respectively, forms single pendulum module 2, spring leaf resonance module 1 and tuning fork resonance module 3 and exists Spacing structure is slided on three sides of bottom plate 5.In other embodiments, the first chute 5-1, the second chute 5-2 and Three chute 5-3 can also be arranged in parallel.
In the present embodiment, the first chute 5-1, the second chute 5-2 and 5-3 points of be listed in the bottom plate 5 three of the 3rd chute Bian Shang, the upper surface at the middle part of bottom plate 5 also set up eccentric wheel resonance module 4.On the one hand the cooperation of chute and slide rail is advantageous to each mould Block it is spacing, another aspect slide rail removes can be in order to will not interfere between each demonstration.In chute end and slide rail both ends Through hole is provided with, and equipped with latch to fixed modules.During demonstration, latch is extracted, each module is pulled out one along chute Measured length, then plug latch, you can complete deployment step.The size of whole device can be effectively reduced during withdrawal, during pull-out just In sufficiently clearly demonstrating.
The composition and function of each module are introduced below.
Referring to Fig. 1 and Fig. 6, the single pendulum module 2 includes being respectively positioned at the first hinged seat 2- at the second slide rail 6-2 both ends The 1 and second hinged seat 2-2, respectively with the first hinged seat 2-1 and the second hinged seat 2-2 is be hinged, top is provided with positioning hole 2-4-1 the first pole 2-3 and the second pole 2-4, and it is spacing in the first pole 2-3 and second by positioning hole 2-4-1 There is swing ball 2-7 working beam 2-6 between bar 2-4, by the suspension wire system of different length.The hinges of the first hinged seat 2-1 and second Joint chair 2-2 jointed shaft difference in height is not less than the first pole 2-3 or the second pole 2-4 thickness, forms the first pole 2-3, the Foldable structures of the two pole 2-4 on slide rail.During without carrying out lecture experiment, working beam 2-6 is removed, and can be by the of both sides One pole 2-3 and the second pole 2-4 fell along jointed shaft, as shown in Figure 6.In use, by the first pole 2-3 of both sides and second Pole 2-4 deploys, then working beam 2-6 is limited between the positioning hole of two poles, as shown in Figure 1.Using the structure of folding, drop Low spatial altitude requirement, the space of the occupancy of single pendulum module 2 can be greatlyd save.
The side of the working beam 2-6 is provided through thin bar 2-5 through hole, one end positioning swing ball of the thin bar 2-5, edge The thin bar 2-5 is axially furnished with pin-and-hole and working beam 2-6 length is passed through by supporting pin regulation thin bar 2-5.During demonstration, The length that thin bar 2-5 passes through working beam 2-6 is adjusted, that is, adjusts the radius of gyration of swing ball in thin bar and makes its swing, can be with It was found that when the suspension wire length of some middle bead is identical with the side band thin bar swing ball radius of gyration, swung on the suspension wire Amplitude of fluctuation can reach maximum.
The spring leaf resonance module 1 includes the wooden seat 1-2 being positioned at by bolt on the first slide rail 6-1, and positioning Two are provided with the steel bar 1-1 of the wooden seat 1-2 sides, length not etc., the steel bar 1-1 of each length.During demonstration, stir wherein Any one steel bar 1-1, can cause the vibrations of other steel bars, examine it can be found that with the steel bar length identical that is struck Steel bar amplitude is maximum, and remaining steel bar amplitude is respectively less than this steel bar.
The tuning fork resonance module 3 includes two tuning fork 3- that be arranged in parallel being positioned at by bolt on the 3rd slide rail 6-3 1, it is arranged on the outside of tuning fork 3-1, has the table tennis 3-2 and mallet of vibrational degrees of freedom.During demonstration, by the parallel pendulum of two tuning forks Put and separate suitable distance, a table tennis is gently pasted into one of tuning fork side and placed.With mallet tap apart from table tennis compared with The tuning fork of distal end, it is found that when the tuning fork vibration tapped by mallet, table tennis can also be upspring, illustrate two tuning forks it Between resonate.
The eccentric wheel resonance module 4 is hinged including one end with vertical gripper shoe 4-1, the other end is by spring 4-3 and bottom The level board 4-2 of the connection of seat 5, motor-driven eccentric wheel 4-5 is set in the free end of the level board 4-2, forms level board The free degree of 4-2 free ends up-down vibration, pen is there is also positioned on level board 4-2, is positioned on bottom plate 5 and display board 4-4 is set.Drill When showing, regulation motor different rotating speeds are rotated with band movable eccentric wheel 4-5 with different rotating speeds, by observing display board 4- under different rotating speeds The motion vestige of pen on 4, it is found that level board 4-2 motion amplitudes reach maximum in a certain rotating speed.Because now water The intrinsic frequency of flat board 4-2 motion frequencies and spring 4-3 below level board 4-2 reaches consistent, and the two resonates.
In summary, the structure of chute and slide rail is set on bottom plate 5, different apparatus for demonstrating, convenient religion are positioned on slide rail Teacher changes apparatus for demonstrating when carrying out different type course, while is also convenient for carrying out the replacing of single assembly, maintenance.
Finish, encapsulated with outer-cover type casing 7, as shown in Figure 5 when bottom plate 5 and all demonstration modules assemble;Outer-cover type casing 7 Connected with bottom plate 5 using hook, be easy to open and encapsulate, other connected modes in the prior art can also be used, setting Carrying handle 7-1 is easy to carry.
