The invention provides a differential pressure transmission multi-diameter split Hopkinson tension-compression integrated bar. The bar comprises a transmission system, a compression bar system, a tension bar system, an absorbing bar, a hydraulic buffer, an optical guide rail, a precise fine tuning strut member and a reshaper, wherein the transmission system, the hydraulic buffer and the precise fine tuning strut member are arranged on the optical guide rail; the compression bar system, the tension bar system and the absorbing bar are arranged on the precise fine tuning strut member; in the compression bar system, the transmission system is arranged on one side of the optical guide rail, an incident compression bar, a transmission compression bar, the absorbing bar and the hydraulic buffer are arranged along the axle center of a gun tube of the transmission system; in the tension bar system, the hydraulic buffer is directly arranged in front of the nozzle of the transmission gun tube; and one side of the optical guide rail is provided with the hydraulic buffer firstly, and then is provided with the transmission system, a tension bar, an incident tension bar and a transmission compression bar in sequence. The Hopkinson tension-compression integrated bar integrates prismatic members with different diameters, namely the prior Hopkinson compression bars and tension bars, onto a set of experiment devices, reduces the cost for purchasing experiment equipment, and has simple installation.
Description
technical field [0001] The invention relates to a high-speed dynamic impact experiment Hopkinson (Hopkinson) pull-and-press rod equipment, in particular to a pressure-difference launching type multi-diameter separated type Hopkinson pull-and-press rod. Background technique [0002] Existing Hopkinson compression rod equipment generally adopts a separate compression rod or a separate pull rod, and a straight rod device with equal cross-section often requires a set of separate launching devices. Some of the launching methods of the launching devices use the manual release of the air valve, which is cumbersome to operate and low in efficiency; while launching using air pressure difference, the volume is not variable, the positioning of the pole and the launching gun is not uniform, and the pole support is fixed and cannot be adjusted, or It is adjustable but the positioning is not uniform, which is very inconvenient for the debugging of experimental work.
