Description
Technical field
The utility model relates to Hopkinson apparatus field, particularly relates to a kind of emitter of Hopkinson equipment.
Background technology
Most of material all shows LOADING RATES to a certain degree or strain rate sensitivity in the mechanical properties such as intensity, the strain rate effect of the short duration pulse of amplitude and the mechaanical property of materials caused by load, very important for the structural design of anti-dynamic load and analysis, these dynamic loads are from conventional weapon penetrative effectt, many military and civilian events such as occasional burst and high-speed impact, Hopkinson bar is acknowledged as the most frequently used experimental facilities 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.
The emitter of Hopkinson equipment is the important component part of Hopkinson equipment, as application number: the patent of 201020169099.5, adopt " left and right end cap, the transmission cylinder that hollow valve rod and cylinder body are formed are divided into two, left and right by middle through cover in the cylinder body of transmission cylinder and launch gas chamber; Axial disjunctor one tracheae in the side of valve opening in middle through cover, the tracheae other end is placed in the circular hole offered in right end cap, and is communicated with the tracheae of the flange be fixed on right end cap; Bomb tube one end is threaded connection the tracheal strips at flange; Launch the pushing tow air chamber that to be provided with between gas chamber and left end cap and to be separated by piston on the left of cylinder body and control air chamber, the end face on the right side of piston and hollow valve rod disjunctor, the other end of hollow valve rod can be sealed and matched with the valve opening of transparent cover centre; Left end cap offers air intake opening and exhausr port, control air chamber cylinder body on offer air intake opening " structure; make " during emission bullet, open the exhausr port of pushing tow air chamber, under the pressure controlling air chamber air pressure, the gas of pushing tow air chamber is squeezed away fast, and promote the valve rod quick sliding left with piston disjunctor, the cone end of valve rod is made to hightail valve opening in middle through cover, be stored in the outside rapid fire of bullet in the gas push bomb tube launched in gas chamber ", thus complete and once launch.
But in this application, structure is very complicated, and manufacturing cost is very high, causes certain burden to enterprise.
Summary of the invention
For the transmitting terminal complex structure of existing Hopkinson equipment, the problem that cost is high, the utility model provides a kind of emitter of Hopkinson equipment, well solves the problems referred to above.
The emitter of described a kind of Hopkinson equipment, be made up of piston, air storage chamber and T-shaped air chamber, its technical scheme is: left side of the present utility model arranges air storage chamber, and right side arranges T-shaped air chamber, and air storage chamber is connected by air flue with T-shaped air chamber; Arrange piston between air storage chamber and T-shaped air chamber, piston is by piston intake hole and air storage chamber UNICOM; Piston nose is provided with O-ring seal; On rear side of piston, piston air chamber is set, is connected by air intake opening extraneous.
The beneficial effects of the utility model are: adopt single cylinder design, and exhausr port and air intake opening are same path simultaneously, reduce the volume of transmitting terminal greatly, and structure is simple simultaneously, with low cost.
Accompanying drawing explanation
Fig. 1 is that the utility model is in and treats inflated condition structural representation; Fig. 2 is the structural representation after the utility model is in inflating pressure.
Wherein, 1. piston; 2. O-ring seal; 3.T type air chamber; 4. air flue; 5. air storage chamber; 6. air intake opening; 7.O type circle; 8. piston intake hole; 9. cylinder body; 10. piston air chamber.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further detailed.
As shown in Figure 1 and 2, an emitter for Hopkinson equipment, be made up of piston 1, air storage chamber 5 and T-shaped air chamber 3, its technical scheme is: left side of the present utility model arranges air storage chamber 5, right side arranges T-shaped air chamber 3, and air storage chamber 5 is connected by air flue 4 with T-shaped air chamber 3; Arrange piston 1 between air storage chamber 5 and T-shaped air chamber 3, piston 1 is by piston intake hole 8 and air storage chamber 5 UNICOM; Piston 1 front end is provided with O-ring seal 2; Piston air chamber 10 is set on rear side of piston 1, connects the external world by air intake opening 6.
The emitter of described a kind of Hopkinson equipment, is provided with O type circle 7 between its piston and cylinder body 9.
Principle of work of the present utility model is: as shown in Figure 1, and piston 1 is in left side, air intake opening 6 air inlet, piston air chamber 10 is inflated, by piston intake hole 8, make air storage chamber 5, piston air chamber 10 and T-shaped air chamber gas 3 press identical, utilize the airtight T-shaped air chamber 3 of piston 1 simultaneously.
During transmitting, air intake opening 6 changes gas outlet venting into, and now piston air chamber 10 air pressure reduces, and T-shaped air chamber 3 air pressure is greater than the air pressure of piston air chamber 10, and piston 1 moves to position as shown in Figure 2.Again perform gas replenishment process, battery has fired.
The utility model mechanism is simple, and launched by the to-and-fro movement of piston, the use on Hopkinson equipment is comparatively ripe.Laid out in parallel of the present utility model can be adopted to realize if need large pressure to launch.
The above is embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
