Description
Technical field
The present invention relates to a kind of Hopkinson bar supporting arrangement for being adapted to many sized samples.
Background technology
Hopkinson bar is a kind of device that can be used to measure stress-strain relation of the material under impact load, is recognized
For be it is the most frequently used it is maximally effective research pulse Under Dynamic Load under the mechaanical property of materials experimental facilities.From Kolsky successes in 1949
Since invention split hopkinson press bar (SHPB), the very big improvement of the experimental provision.By inspection information, find to work as
The test specimen that modern Hopkinson bar experiment is used is generally cylinder, and experiment shows, for the large scale Hopkinson less than 75mm
Lever apparatus, when concrete material piece lengths are less than 25mm, friction effect influences larger to test result；When piece lengths are big
When 90mm, reflected tensile effect is obvious, it is impossible to reflect the true dynamic mechanical of material；When piece lengths are 30~75mm,
That is draw ratio L/D ≈ (0.4~1.0), are capable of the dynamic mechanical of reaction material exactly.Meanwhile, present science and techniques of defence are big
Learn professor Lu Fangyun have developed diameter can in the range of 20-50mm continuously adjustabe split hopkinson bar device, one
The fixed scope of experiment for expanding experiment test specimen diameter.
But due to the popularity and frequency tested, there is following deficiency in existing Hopkinson bar support meanss：
The diameter of the test specimen that the split hopkinson bar device the 1st, developed can be supported is relatively simple, adjusting range
It is limited；And piece lengths are usually no more than 200mm, so that the scope of experiment has certain limitation, it is impossible to meet piece lengths
Consecutive variations adjustable need, it is impossible to meet big diameter, the requirement of experiment of length test specimen more long and experimental precision.
2nd, existing split hopkinson bar apparatus system substantially has V-shaped groove, linear bearing shape and rolling stock shape etc.；
V-groove type axial sliding resistance is too big, so as to produce experimental error, influences experimental result, it is impossible to ensure the accurate of experimental data
Property and science；There is limited specification, dismounting inconvenience and be easy in linear bearing, it is impossible to adapt to the adjustable need in bar footpath
Will；Rolling stock type positioning is still not high enough.
3rd, with the increase of test specimen diameter, existing supporting arrangement is got over and is not easy to support test specimen, is difficult to provide strong in an experiment
Powerful support, it is impossible to ensure the stability of test specimen, there is certain influence on the accuracy of experimental result.
4th, the most positioning datum of system is relatively unified, but positioning precision is not still high, causes leverage axiality not high, receives
Power is uneven, and rod bending, wave distortion, poor repeatability of experiment etc. are easily caused in experiment.
The content of the invention
In order to overcome existing Hopkinson bar support pattern can only measure single diameter test specimen, stability is low and error is big
Deficiency, it is suitable many that the present invention provides that a kind of easy to use, simple to operate, measurement range is big, stability is high and practical
The Hopkinson bar supporting arrangement of sized samples.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of Hopkinson bar supporting arrangement for being adapted to many sized samples, including removable rail brackets and at least two footpaths
To replaceable bearing assembly, the radial direction replaceable bearing assembly includes portable bottom support bracket and side supporting member, the shifting
The top of dynamic formula bottom support bracket is support member, and bottom is moving parts, and the support member is in groove type, side supporting member point
It is left supporting member and right support part, the left supporting member and right support part specular are set, the left supporting member and right supporting
It is fixed in the groove of the support member, the cambered surface of the left supporting member and right support part is formed for Hope's gold part replaceable
The station that gloomy bar is placed；The moving parts is movably sleeved on the removable rail brackets.
Further, the arc of installation center pulley in the middle of the bottom land of the support member, the left supporting member and right support part
Truckle is installed on face.
Further, mortise is set in central pulley both sides, the left supporting member and right support part are respectively equipped with tenon, institute
Tenon is stated to be plugged in the mortise.
The removable rail brackets includes support and guide rail, and on support, the moving parts can for the track installation
Movably it is sleeved on the guide rail.
The moving parts is guide rail ring, and the guide rail ring lower section is button latch fixing device, on the guide rail
Location hole is provided with, the button latch fixing device coordinates with the location hole.
The button latch fixing device includes latch button, and the latch button is positioned at support through the location hole
On.
The support includes support base plate and rear side fixed plate, and the latch button is positioned in the rear side fixed plate.
One end of the support sets screw, and the opposite side of the support sets sea whelk.
Beneficial effects of the present invention are mainly manifested in：1st, by radial direction replaceable supporting arrangement and removable rail brackets,
Meet the test requirements document of sizes test specimen.2nd, the roller on supporting arrangement can rub the slip of test specimen and device contact portion
Wiping is changed into more favourable rolling friction, reduces test error.3rd, side supporting member and the mutual joggle of base, and can be used some
Individual radial direction replaceable supporting arrangement, is beneficial to support test specimen, it is ensured that test specimen stability.4th, positioning precision is high, installs, dismantles letter
Just, it is easy to operation.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Reference picture 1~Fig. 4-3, a kind of Hopkinson bar supporting arrangement for being adapted to many sized samples, including portable bottom
Bearing, side set of bearings are into having four kinds of specifications.
Left and right side supporting member can be changed according to the diameter of test specimen, be primarily adapted for use in four kinds of different sizes suddenly
Pu Jinsen bar test specimens, the diameter in four kinds of specifications is respectively 25mm, 50mm, 75mm, 100mm.Pulley and side in the middle part of concave groove
Pulley on the support member of side can reduce the sliding friction of test specimen, improve the accuracy of experiment.
Portable bottom support bracket：Overall dimension 200mm long, 140mm high, 30mm wide, as shown in the figure.Bottom support bracket is divided to two
Point, top is supporting member, and bottom is moving parts.
Portable bottom support bracket top is concave groove, and groove depth 30mm, bottom is 20mm with side frid thickness；In the middle of bottom land
It is mounted with a central pulley of Φ 30, and pulley top slightly above wooden unit upper surface；In pulley both sides away from pulley center 40mm
Respectively there is an a diameter of 20mm at place, and depth is the mortise of 15mm, for side supporting member phase joggle.
Bottom is that guide rail ring is arranged on support guide, and annulus interior diameter is 40mm, and overall diameter is 50mm, and thickness is
5mm, is button latch fixing device under guide rail ring, and 145mm long, plug section is the circle of Φ 40, and button section is Φ's 26
