Abstract
The utility model relates to a compression experiment device of a Hopkinson pressure bar and particularly relates to a compressed sample positioning device of the Hopkinson pressure bar. The compressed sample positioning device comprises a compressed input bar and a compressed transmission bar, and further comprises a sleeve-shaped positioning sleeve connected with the compressed input bar and the compressed transmission bar, wherein the positioning sleeve is internally provided with a plurality of stand columns; and arc-shaped grooves for containing the compressed input bar and the compressed transmission bar are formed in the stand columns.
Description
Technical field
The utility model relates to a kind of Hopkinson pressure bar compression test device, specifically a kind of compression sample locating device of Hopkinson pressure bar.
Background technology
Most of materials are at the LOADING RATES or the strain rate sensitivity that all show aspect the mechanical properties such as intensity to a certain degree, the strain rate effect of the short duration pulse of high amplitude and the caused mechaanical property of materials of load, structural design and analysis for anti-dynamic load are very important, these dynamic loads are from conventional weapon penetration and blast, many military and civilian events such as occasional burst and high-speed impact, Hopkinson bar is acknowledged as the experimental facilities of the mechaanical property of materials under the most effective the most frequently used research pulse dynamic load effect, it is not only applicable to compression experiment, can also successfully stretch, shear and frictional wear experiment, and can expand to and have acceleration, power and pressure sensor calibrating function.When needs carry out compression experiment to sample, for traditional Hopkinson pressure bar compression test device, usually will be after compression incident bar and compression transmission bar be fixed on the guide rail, to compress sample with hand is placed between compression incident bar and the compression transmission bar, apply a pair of power in opposite directions for then two bars, prevent that sample from coming off, open the gas ejecting gun afterwards again and make projectile impact compression incident bar carry out compression experiment, sample often comes off easily like this, and it is very inconvenient to operate.
The utility model content
In order to solve the problems of the technologies described above, the utility model provide a kind of can be fast, the accurate compression sample locating device of the Hopkinson pressure bar of location, easy to use, quick.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of compression sample locating device of Hopkinson pressure bar, comprise compression incident bar and compression transmission bar, also be provided with and connect compression incident bar and the cover tubular locating sleeve that compresses transmission bar, be provided with column in the locating sleeve, be used for holding the contracting incident bar and be arranged on column with the deep-slotted chip breaker that compresses transmission bar.
Selection as optimum, the zone that forms between the inside surface of deep-slotted chip breaker and the inside surface of locating sleeve can with compression incident bar clearance fit, can be directly during use the compression sample be placed into deep-slotted chip breaker inside, will compress incident bar afterwards again and compress transmission bar and insert respectively and carry out next step operation in the locating sleeve.
As further setting, described locating sleeve is Openworks shape, is convenient to observe in experimentation the variation of sample.
Beneficial effect: the compression sample locating device of a kind of Hopkinson pressure bar of the utility model is provided with a locating sleeve between compression incident bar and compression transmission bar, be provided with deep-slotted chip breaker in the locating sleeve, be used for holding compression incident bar, compression sample and compression transmission bar, the accurate location that can realize compression sample in the compression experiment easily and efficiently.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model: a kind of compression sample locating device of Hopkinson pressure bar, compression incident bar 11 as shown in Figure 1 and compression transmission bar 13, between arranges the locating sleeve 12 of cover tubular, the inside surface of locating sleeve 12 is provided with many highly identical columns 121, as Fig. 2, Fig. 3, deep-slotted chip breaker 122 is arranged on the column 121, the inside surface radian of deep-slotted chip breaker 122 adapts with compression incident bar 11, guarantees to compress incident bar 11 and can be placed in the deep-slotted chip breaker 122 and along it with compression transmission bar 13 and be free to slide.
Constitute between the inside surface of the inside surface of deep-slotted chip breaker 122 and locating sleeve 12 and hold compression incident bar 11 and the space of compressing transmission bar 12, be similar to clearance fit, firm by the support between two bars, after locating sleeve 12 is assembled between compression incident bar 11 and the compression transmission bar 13, stick foil gauge 14 in the relevant position, on the guide rail that whole device is put into Hopkinson pressure bar, can bring into use.
