Description
Technical field
The utility model relates to a kind of novel test specimen bracing or strutting arrangement for separating of formula Hopkinson pressure bar experiment.
Background technology
Split hopkinson press bar (SHPB) experimental provision is the dynamic impact compression experimental provision of current testing material dynamic property experiment, SHPB experimental provision can transmitted at high speed bullet and test material clash into load, SHPB experiment test system is usually by drop bar (bullet), incident bar, transmission bar, absorbing rod, snubber assembly and measuring system composition (as shown in Figure 1), drop bar and incident bar collision rift are applied to incident bar impact, this impact is by incident bar-test specimen-transmission bar-absorbing rod, finally by the snubber assembly being arranged on absorbing rod rear end, impact is cushioned, absorb, in SHPB system, incident bar, transmission bar etc. all need to be supported by bracing or strutting arrangement, simultaneously, according to one-dimension stress wane hypothesis and test specimen stress equilibrium hypothesis, each depression bar is when collision, each impingement area needs well to combine, when collision, excesssive gap or striking face do not fit like a glove, experiment can produce very large error even mistake, and the clamping of some soft material and fixing very difficult, this just requires that incident bar, test specimen, transmission bar have good right alignment, at present, the incident bar, transmission bar etc. of Hopkinson pressure bar device usually adopt and carry bracing or strutting arrangement and support, and coaxial precision is very high, but test specimen and incident bar, right alignment between transmission bar are difficult to ensure.
Summary of the invention
The utility model makes improvement to above-mentioned prior art Problems existing, namely the purpose of this utility model is to provide a kind of novel test specimen bracing or strutting arrangement for separating of formula Hopkinson pressure bar experiment to solve existing Hopkinson pressure bar experiment device incident bar-test specimen-transmission bar disalignment, thus affects the problem of experimental result.
The technical solution adopted in the utility model is:
The novel test specimen bracing or strutting arrangement for separating of formula Hopkinson pressure bar experiment, it comprises test specimen bracing or strutting arrangement, it is characterized in that between base, support bar I, adjustable stud, support bar II and is be fixedly connected with between support bar II, sleeve I; Sleeve I is connected by wedge-shaped slot with sleeve II; Base adopts with support bar II and is threaded, and support bar I is connected by the screw thread at the upper and lower two ends of adjustable stud with support bar II; Sleeve I internal diameter is identical with the diameter of incident bar and transmission bar, and sleeve II internal diameter is identical with test specimen diameter, and sleeve I has wedge-shaped slot and closely cooperates with sleeve II, and sleeve I is with sleeve II is coaxial and material is identical; Be permanent connection between support bar II with sleeve I, this device adopts and glueds joint.
The beneficial effects of the utility model are:
(1) the utility model design of part is simple, connects reliable, is easy to processing;
(2) be between base, support bar I, adjustable stud and support bar II and be threaded, the height of adjustable sleeve I, and then sleeve I and incident bar (transmission bar) are fitted tightly, to ensure its right alignment, and easy to use;
(3) be permanent connection (this device adopts and glueds joint) between support bar II with sleeve I, ensure its stability;
(4) sleeve I has wedge-shaped slot and closely cooperates with sleeve II, makes sleeve I coaxial with sleeve II, thus ensures that incident bar (transmission bar) is coaxial with test specimen, reduces experimental error.
