Abstract
A teaching demonstration model for vibration damping effect of vibration damping materials comprises a vibration generator, a vibration detector, vibration damping material with a round hole in a center, a central support screw rod, a base, a transparent sidewall, a top cover, a guide line, a switch and a display screen. The vibration generator capable of producing fixed amplitude and frequency is employed as a vibration source, the vibration detector capable of measuring parameters of amplitude and frequency is employed as a receiving device, vibration damping materials with different materials and thicknesses are placed between the vibration source and the detector, various parameters displayed by the vibration detector display screen are recorded, and influence rules to vibration damping effect by vibration damping materials of different materials and thicknesses can be observed under vibration of fixed amplitude and frequency parameters.
Description
Technical field
The utility model relates to a kind of demonstration model for teaching, relates in particular to a kind of demonstration model for teaching of damping material effectiveness in vibration suppression.
Background technology
Along with the progressively quickening of development in science and technology, corresponding environmental pollution also produces thereupon, and vibration pollution is a kind of of environmental pollution.Vibration surpasses certain boundary, can produce infringement to health and facility, people's live and work environment formation is disturbed, or made machine, equipment and instrument cisco unity malfunction.Vibration pollution has seriously influenced the mankind's normal productive life.
Only can be by the mode of oral account or video in vibration pollution teaching now, allow the student understand the principle of vibration damping and affect the factor of effectiveness in vibration suppression, and can't get information about the actual effect of vibration damping, and not yet someone designs a kind of demonstration model for teaching of damping material effectiveness in vibration suppression so far.
The utility model content
For the problems referred to above, it is a kind of easy to carry, simple to operate that the utility model provides, and can demonstrate the demonstration model for teaching of damping material effectiveness in vibration suppression.
The technical scheme that its technical matters that solves the utility model adopts is: vibration machine, vibrating detector, the round-meshed damping material of center tool, central supporting screw rod, base, transparent sidewall, upper cover, wire, switch and display screen.Vibrating detector is fixed on base, the central supporting screw rod is fixed on the vibrating detector center, central supporting screw rod side curl, vibration machine closely is connected with the central supporting screw rod by spiral way, and can regulate distance between itself and vibrating detector by rotation.Display screen can show the various vibration parameters that detect.The utility model is the damping material of unlike material, thickness fixedly, and described damping material has 10 kinds of unlike materials, and the thickness of every kind of material has 10 kinds of specifications.All there is circular hole at different damping materials center, and Circularhole diameter is 1.5 times of central supporting screw rod diameter.
The beneficial effects of the utility model are to demonstrate under fixed amplitude, frequency the effectiveness in vibration suppression of unlike material, thickness damping material.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In Fig. 1: 1 base, 2 transparent sidewalls, 3 upper covers, 4 vibrating detectors, 5 central supporting screw rods, 6 vibration machines, 7 damping materials, 8 wires, 9 switches, 10 display screens.
Embodiment
Wire (8) connects vibrating detector (4) by base (1).Central supporting screw rod (5) is fixed on vibrating detector (4) center; Vibration machine (6) is fixed on central supporting screw rod (5) in a spiral manner, the rotatable adjustment of distance between vibration machine (6) and vibrating detector (4).Damping material (7) is placed between vibration machine (6) and vibrating detector (4).Base (1), transparent sidewall (2) and upper cover (3) form shell together.Open switch (9), vibration sounding device (6) produces the vibration of preset parameter, is delivered to vibrating detector (4) by damping material (7), display parameter in display screen (10).Can perhaps change the damping material of same thickness unlike material by changing the damping material of identical material different-thickness, draw respectively the relation between effectiveness in vibration suppression and damping material material, thickness.
Claims (1)
