Abstract
The utility model discloses a 2m/s impact tester comprising an impact inclined platform, a slide track, a test sample platform, an impact stop piece, electromagnets, a traction iron piece, a traction motor and a test sample fixing plate; the slide track if fixed on the impact inclined platform; the test sample platform slides in the slide track; the electromagnet is correspondingly arranged on the test sample platform and the traction iron piece; the test sample platform is provided with the test sample fixing plate used for fixing a tested object; the impact stop piece is arranged on a lower end of the impact inclined platform. The 2m/s impact tester employs an inclined platform gravity acceleration mode, the test sample is placed on the test sample platform sliding along the inclined platform track, thereby greatly preventing disadvantages caused by conventional device guide rail limitation; the test employs a potential-to-kinetic energy principle, so track sliding energy loss can be removed, thereby accurately and stably providing 2m/s horizontal speed, a motor traction rope is hardly broken, and simultaneously an occupation space of the tester can be saved.
Description
Technical field
The utility model relates to a kind of scooter and child's tricycle performance aircraft, relates in particular to a kind of 2m/s collision tester.
Background technology
Conventional collision tester is to be mainly made up of motor accelerator, horizontal dragging track, collision block at present.The wheel of test specimen is placed on horizontal dragging track, pulls test specimen by accelerator, when test specimen is in the time that horizontal sliding speed reaches 2m/s, collision block, off-test.But, provide because 2m/s horizontal velocity relies on motor accelerator, its speed calculates by timer, in actual operation, be easy to be subject to timer susceptibility and test specimen to affect with the track situation of being combined, be difficult to provide 2m/s horizontal velocity accurately and reliably.
It is spacing that prior device need fill guide rail, in test process, the wheel that slides main dependence test specimen of test specimen slides realization on dragging track, the center of gravity deviation of test specimen, the combination situation of the size of wheel and wheel and track makes test specimen very unstable in the process of sliding.Too fast speed can cause sample to depart from from guide rail, excessively causes slowly testing inaccurate.Unsettled speed also makes the rope of traction often can rupture, and causes test specimen to damage, and test is forced to Halfway Stopping, has a strong impact on test process.Moreover determining of 2m/s horizontal velocity mainly relies on two parallel relative timers, impact velocity all will be debugged sensor before being easily subject to the susceptibility of sensor to affect each test, and the debugging of sensor, has spent a large amount of time.
Utility model content
For solving existing problem in above-mentioned prior art, the utility model provides a kind of 2m/s collision tester.
The utility model adopts following technical scheme to realize: a kind of 2m/s collision tester, comprise shock sloping platform, dragging track, test specimen platform, collision block, electromagnet, traction iron block and test specimen fixed head, described dragging track is fixed on described shock sloping platform, described laboratory sample platform slides in described dragging track, on described laboratory sample platform and described traction iron block, correspondence is provided with described electromagnet, described laboratory sample platform is provided with the described laboratory sample fixed head for fixing determinand, described collision block is arranged on described shock sloping platform low level one end.
Preferably, this 2m/s collision tester also comprises traction electric machine and be arranged on the fixed pulley on described shock sloping platform, and the rope of described traction electric machine is walked around described fixed pulley and is fixedly connected with described traction iron block.
Preferably, this 2m/s collision tester also comprises the removable pulley being arranged on framework, is useful on the rope of fixing determinand on described removable pulley.
Compared with prior art, the utlity model has following beneficial effect: the mode that the utility model adopts sloping platform gravity to accelerate, test specimen is positioned on test specimen platform, test specimen platform slides along sloping platform track, avoid widely the spacing drawback of bringing of prior device guide rail, test adopts potential energy to be converted into the principle of kinetic energy, remove the energy loss that track slides, the horizontal velocity of 2m/s can be accurately provided stably, the rope of motor traction is also not easy fracture, the occupation of land space of also having saved testing machine simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with specific embodiment, a kind of 2m/s collision tester of the utility model is described in further detail.
As shown in Figure 1, the utility model proposes a kind of 2m/s collision tester, comprise and clash into sloping platform 1, dragging track 2, test specimen platform 3, collision block 4, electromagnet 5, removable pulley 6, fixed pulley 7, traction iron block 8, test specimen fixed head 9, dragging track 2 is fixed on and clashes on sloping platform 1, laboratory sample platform 3 slides in dragging track 2, on laboratory sample platform 3 and traction iron block 8, correspondence is provided with electromagnet 5, laboratory sample platform 3 is provided with the laboratory sample fixed head 9 for fixing determinand, collision block 4 is arranged on and clashes into sloping platform 1 low level one end, on removable pulley 6, be useful on the rope of fixing determinand, to guarantee that in test process, determinand can not throw away because of collision laboratory sample platform 3, fixed pulley 7 is fixed on and clashes on sloping platform 1, clash on sloping platform and have aperture, clash into sloping platform 1 inside and be provided with traction electric machine, the rope of traction electric machine sees through this aperture and walks around fixed pulley 7 and is fixedly connected with traction iron block 8.
When test, determinand is fixed on to laboratory sample platform, again by the electromagnet energising adhesive on electromagnet and the laboratory sample platform of traction iron block, pull rope that laboratory sample is risen to certain altitude along dragging track by being placed in the traction electric machine of sloping platform inside, by electromagnet power-off, the low level that allows the free skating of laboratory sample platform drop down onto laboratory sample platform makes determinand and the collision of collision block again.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; any be familiar with those skilled in the art the utility model disclose technical scope in, the variation that can expect easily or replacement, all should be encompassed in protection domain of the present utility model in.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
