Abstract
The invention discloses a teaching demonstration model for the vibration-absorbing effect of a vibration-absorbing material. The teaching demonstration model comprises a vibration generator, a vibration detector, the vibration-absorbing material with a hole in the center, a central supporting screw rod, a base, a transparent side wall, an upper cover, a guide wire, a switch and a display screen. The teaching demonstration model has the advantages that the vibration generator capable of generating fixed vibration amplitude and frequency can be used as a vibration source, the vibration detector capable of measuring the parameters of the vibration amplitude and the frequency and the like can be used as a receiving device; all the parameters displayed by the display screen of the vibration detector are recorded by placing the vibration-absorbing materials with different materials and thicknesses between the vibration source and the detector, and the influence rule of the vibration-absorbing materials with different materials and thicknesses to the vibration-absorbing effect under the vibration with the parameters such as the fixed vibration amplitude and the frequency is inspected.
Description
Affiliated technical field
The present invention relates to a kind of demonstration model for teaching, relate 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 human normal productive life.
Only can be by the mode of oral account or video in the now vibration pollution teaching, 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.
Summary of the invention
For the problems referred to above, the invention provides a kind of easy to carryly, simple to operate, and can demonstrate the demonstration model for teaching of damping material effectiveness in vibration suppression.
The technical solution adopted for the present invention to solve the technical problems is: vibration machine, vibrating detector, the round-meshed damping material of center tool, central supporting screw rod, base, transparent sidewall, loam cake, wire, switch and display screen.Vibrating detector is fixed on the base, the central supporting screw rod is fixed on the vibrating detector center, central supporting screw rod side curl, vibration machine closely links to each other with the central supporting screw rod by spiral way, and can regulate distance between itself and the vibrating detector by rotation.Display screen can show the various vibration parameters that detect.The present invention 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 invention has the beneficial effects as follows, can demonstrate under fixed amplitude, frequency, the effectiveness in vibration suppression of unlike material, thickness damping material.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
Among Fig. 1: 1 base, 2 transparent sidewalls, 3 loam cakes, 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 the central supporting screw rod (5) in a spiral manner, the rotatable adjustment of distance between vibration machine (6) and the vibrating detector (4).Damping material (7) is placed between vibration machine (6) and the vibrating detector (4).Base (1), transparent sidewall (2) and loam cake (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, the thickness.
Claims (1)
1. the demonstration model for teaching of a damping material effectiveness in vibration suppression comprises: vibration machine, vibrating detector, the round-meshed damping material of center tool, central supporting screw rod, base, transparent sidewall, loam cake, wire, switch and display screen; It is characterized in that, vibrating detector is fixed on the base, the central supporting screw rod is fixed on the vibrating detector center, central supporting screw rod side curl, vibration machine closely links to each other with the central supporting screw rod by spiral way, and can regulate distance between itself and the vibrating detector by rotation.
