Specific embodiment
It is this utility model structural representation referring to accompanying drawing 1.In figure：
For the device of research collision, including base 1 made by flat board, the plane that base 1 is located is horizontal plane, base 1
Most handy steel plate is made, if the necessity studied, it is also possible to made with oak floor.Vertical support 2 is fixedly connected with base 1,
Vertical support 2 can be made with straight reinforcing bar, and vertical support 2 is arranged at vertical direction, it is characterized in that：Also include overhead gage 3, on
Baffle plate 3 is a horizontally disposed flat board, means overhead gage 3 in horizontal plane, and overhead gage 3 is fixedly connected with vertical support 2,
Overhead gage 3 is provided with the first hole 31, and the first hole 31 is a through hole；
Also include lower baffle plate 4, lower baffle plate 4 is located at the lower section of overhead gage 3, and lower baffle plate 4 is a horizontally disposed flat board, is meant
Say that lower baffle plate 4 removably connects in horizontal plane, lower baffle plate 4 and vertical support 2, so convenient installation straight-bar 5, and
Lower baffle plate 4 can be moved up and down along vertical rack, and lower baffle plate 4 is provided with the second hole 41, and the second hole 41 is a through hole；
Lower baffle plate 4 can be moved up and down along vertical rack, can eaily determine the height that upper ball 7 rebounds, example
Such as：Just the lower surface of lower baffle plate 4 is reached after allowing ball 7 to rebound, is so easy for measuring the height of bounce-back, also, also held
Easily determine distance of the upper ball 7 apart from base, for example：The top of ball 7 is allowed to contact the lower surface of lower baffle plate 4 just, then, upper ball
7 tops are exactly distance of the lower baffle plate 4 apart from base apart from the distance of base.
First hole 31 and the second hole 41 are in same vertical curve；
Also include for through the straight-bar 5 in the first hole 31 and the second hole 41, the lower ball 6 of the lower end of straight-bar 5 connection, lower ball 6 and straight
Bar 5 removably connects, and lower ball 6 is shaped as spheroidal, the centre of sphere that the vertical curve that straight-bar 5 is located passes through lower ball 6；
Also include the upper ball 7 for colliding with lower ball 6, upper ball 7 is shaped as spheroidal, and upper ball 7 is provided with one by straight
The through hole in footpath, upper ball 7 is sheathed on straight-bar 5；
The lower end of upper ball 7 and the upper-end contact of lower ball 6.
Further：Quality of the quality of upper ball 7 less than lower ball 6.
Further：The horizontal cross-section of straight-bar 5 is circular, a diameter of 1cm, and its cross section of the through hole that upper ball 7 is provided with is round
Shape, a diameter of 1.2-1.5cm.
Further：Straight-bar 5 is made of clear material.So it is easy to observer that sight line is focused on upper ball 7, lower ball 6.
Further：Height of the height of straight-bar 5 more than overhead gage 3 to base 1.So can allow straight-bar 5 release with
Also it is unlikely to afterwards to topple over.
Further：Generally circular in shape, the diameter 1.2cm in the first hole 31, the second hole 41 it is generally circular in shape, it is a diameter of
1.2cm, the horizontal cross-section of straight-bar 5 is circle, a diameter of 1cm.
Further：Vertical support 2 is additionally provided with the scale for measuring height.
Using method：
The first step, measurement：The quality of lower ball 6, the quality of upper ball 7；
Second step, lower ball 6 lower end of straight-bar 5 is installed to, and upper ball 7 is sheathed on straight-bar 5；
3rd step, allow straight-bar 5 top through the second hole 41, the first hole 31, operator is with portable the top of straight-bar 5；
4th step, operator's release straight-bar 5, straight-bar 5 drops together with upper ball 7, lower ball 6, collides base 1, then, lower ball
6 can rebound, and upper ball 7 also can rebound.
In aforesaid operations, it is related to these collisions：1, the collision of lower ball 6 and base 1.2, the collision of lower ball 6 and upper ball 7.
The height of the bounce-back of upper ball 7, the height of the bounce-back of lower ball 6, depending on the property and upper ball 7, the quality of lower ball 6 of collision material.
As qualitative investigation, it may not be necessary to the height of strict measurement bounce-back.If necessary to quantitative measurement, can be with this
Sample：Vertical support 2 is additionally provided with the scale for measuring height.The process of collision is recorded with video camera, it is possible to be more prone to
See the height of bounce-back.
Why first hole 31, the second hole 41 are setBecause a hole is it is difficult to ensure that straight-bar 5 is always positioned at vertical side
To two holes are easy for allowing straight-bar 5 to be located at vertical direction.
In this collision process, if collision can be considered as elastic collision, the quality of upper ball 7 is less than the quality of lower ball 6,
The height of the bounce-back of upper ball 7 can be very high, can theoretically be calculated this result, it is possible to use this device proof theory is calculated
Result.
This utility model using method is various, simple structure, low cost, and for research collision new technical scheme is provided.
