Description
Technical field
The present invention relates to a kind of emitter of Hopkinson pressure bar, specifically a kind of bullet emitter 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 most frequently used experimental facilities of the most effectively studying the mechaanical property of materials under pulse Under Dynamic Load, it is not only applicable to compression test, can also successfully stretch, shear and friction-wear test, and can expand to and there is acceleration, power and pressure sensor calibrating function. in the time using Hopkinson pressure bar to test, need to be in its transmitting tube loading, then utilize gases at high pressure and by its pressure abrupt release, bullet is got out, impact experiment apparatus, traditional Hopkinson pressure bar is all to insert from the mouth of pipe of transmitting tube in the time of loading, because transmitting tube is long, so need bullet be headed into transmitting tube end with iron wire, the very trouble that operates, and lose time.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of bullet emitter of Hopkinson pressure bar that can rapid reloading bullet.
The present invention for solving the problems of the technologies described above adopted technical scheme is: a kind of bullet emitter of Hopkinson pressure bar, comprise brace table, be fixed on the base of the emission cavity on brace table, the transmitting tube being connected with emission cavity and bearing support platform, on brace table, be provided with along its length the sliding support for supporting transmitting tube, be provided with port at transmitting tube near one end of emission cavity, port place is provided with hermatic door.
The present invention is provided with port at transmitting tube near one end of emission cavity, and port place is provided with hermatic door, in the time using Hopkinson pressure bar to fill bullet, can directly open hermatic door, and bullet is inserted in transmitting tube, carries out next step operation.
As further setting, the side of port is provided with cotter way, the side of hermatic door is provided with and the corresponding slideway of cotter way, hold-open catch is housed in slideway, make hermatic door in the time of closed condition, can promote hold-open catch along slideway it is entered in cotter way, the pin of increase plugs together fixing structure and can be good at hermatic door to be fixed on transmitting tube, avoid excessive in use impact air-flow that hermatic door is backed down, cause security incident; On emission cavity, be connected with nitrogen tube, when use, be used for passing into high pressure nitrogen in emission cavity, as the power source in emission cavity.
As further setting, on brace table, be provided with chute along brace table bearing of trend, the bottom of sliding support is provided with and chute projection accordingly, and sliding support can be slided along chute, can select easily the fixed position of sliding support since like this.
As further setting, on described brace table, offer shock relieve vent, slow down the impact concussion of Hopkinson pressure bar in the time of emission bullet.
Beneficial effect: the bullet emitter of a kind of Hopkinson pressure bar of the present invention is provided with port at transmitting tube near one end of emission cavity, port place is provided with hermatic door, compared with traditional device, the present invention can make bullet pack transmitting tube end into from port, need not insert bullet from the mouth of pipe of transmitting tube again, then head into transmitting tube with iron wire, the filling that this just greatly facilitates bullet, has improved service efficiency.
