The invention provides a novel split Hopkinson pull bar apparatus for solving problems existing in present split Hopkinson pull bars, and relates to the material dynamic mechanical performance experiment equipment field. The novel split Hopkinson pull bar apparatus mainly comprises an absorption bar, a hollow incident bar, a high-pressure gas room, an impact plug, an impact bar, a hollow transmission bar and a filling plug. The impact bar (bullet) moves long the inner wall of the incident bar under the driving of the high-pressure gas in the high-pressure gas room, impacts the impact plug under a certain speed, and forms a stretching pulse in the incident bar. The novel split Hopkinson pull bar apparatus can make up the defects of the present novel split Hopkinson pull bars, and can satisfy experiment research requirements of concrete materials and other materials having uneven internals; and the novel split Hopkinson pull bar apparatus has the advantages of reasonable structure design, and high quality of the stretching pulse generated in the incident bar, so the effectiveness of an experiment result is further guaranteed.
