Abstract
The utility model relates to a dynamic testing equipment split hopkinson pressure bar's support adjusting device, including being used for the base of improving level and sliding and adjust at supporting platform, be provided with a plurality of adjusting bolt of fixing a position of going on when being used for the horizontal sliding to adjust on the base, still offer the V type locating surface that is used for the depression bar to support on the base, inlay on the V type locating surface and be equipped with a plurality of location pilot pin, between location pilot pin and the V type locating surface, all be provided with between base and the supporting platform and be used for the fastener that links firmly. This dynamic testing equipment split hopkinson pressure bar's support adjusting device simple structure, the location support precision is high, adjusts convenient and reliablely, the terminal polished rod and the round angle structure that falls of adjusting bolt reduces the friction between adjusting bolt and supporting platform when improving positioning accuracy, improve adjusting bolt's life, V type locating surface has self -align function, positioning accuracy is high, location pilot pin positioning accuracy is high, fixed reliable.
Description
Technical field
The utility model provides a kind of supporting and regulating device of dynamic test equipment split hopkinson press bar, is particularly applied to Measurement of Material Mechanical Performance, belongs to mechanical field.
Background technology
SHPB(Hopkinson pressure bar) experimental provision is the impact loading device of current experiment, SHPB experimental provision can transmitted at high speed bullet and test material clash into load, SHPB experiment test system usually by incidence, transmission, energy-absorbing bar, and snubber assembly composition, bullet and incident bar collision rift are applied to incident bar impact, and this impact passes through incident bar, test specimen, finally propagate into absorbing rod, the snubber assembly being arranged on absorbing rod rear end the impact of absorbing rod will be cushioned, absorbs; In SHPB system, incident, transmission, energy-absorbing bar all needs to be supported by bracing or strutting arrangement, simultaneously, according to stress wave principle, each depression bar is when collision, and 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 at present, Hopkinson pressure bar bracing or strutting arrangement adopts pad to regulate its height usually, faying face about bottom surface adopts bolt to regulate it, this very difficult adjustment puts in place, waste a large amount of experimental periods, and precision is lower.
Utility model content
