Description
Technical field
The utility model belongs to motor vehicles explosion-proof technical field, particularly one can allow tester test among a small circle, can obtain the protection type vehicle bottom explosion environment analogue means of high accuracy experiment data while ensureing explosion environment security.
Background technology
Be directed to the bottom explosive test of protection type vehicle, be all in most cases that fixed point blast is carried out in the spacious place of selection one, therefore before explosive test, tester will spend certain manpower and financial resources to be set up with cloth choosing of test site.Faced with this situation, also there is no a kind of device can simulating protection type vehicle experience bottom pyroshock environment at present, when small-scale test site is carried out explosive test, both effectively explosion wave can be weakened, for the personal safety of tester is given security, the test figure of degree of precision can be obtained again.
In order to solve the problem effectively weakening the shock wave that blast produces, it is the spherical device with shell that Chinese patent (application number: 03826155 publication date: on April 12nd, 2006) discloses a kind of inside, whole device comprises upper and lower two parts, top is divided into U-shaped conduit, and it is formed with the closed chamber of lower part and is communicated with.Lower part is roughly the chondritic of upper end open, and it comprises two layer closed areas, and outermost layer and middle layer form the spheroid chamber of a hollow jointly; Innermost layer is the right cylinder of uncovered, and it and middle layer form another and wrap up the larger closed chamber in region, and in chamber, most of region all fills the fluid of high compression quality.The explosion wave being applied to innermost layer that explodes when explosion happens causes pressure in shell to raise, internal fluid pressure is raised and gas and liquid will be caused upwards to be shifted by U-shaped pipe, the energy that the energy conversion exploded consumes for fluid displacement in shell, corresponding Blast Shock will weaken.
United States Patent (USP) (application number: 99811450 publication date: on July 3rd, 2002) discloses in the bottom of closed container, both sides and top layout blast padded coaming reach the method weakening explosion wave.Specific embodiment is that the shape that blast padded coaming is cut into each face of closed container the same is attached to container inner wall, directly fills up impact-attenuating material at groove.For the seam crossing of two panels blast padded coaming, take the mode of hot melt to sew up.So just forming a complete totally enclosed blast padded coaming separation layer in closed container inside, when running at internal tank explosive event, just can weaken the damage to peripheral personnel and object.
Therefore, prior art Problems existing is: tester cannot be allowed to test among a small circle, thus can not obtain high accuracy experiment data while the security of guarantee explosion environment.
Summary of the invention
The purpose of this utility model is to provide a kind of protection type vehicle bottom explosion environment analogue means, and tester can be allowed to test among a small circle, can obtain high accuracy experiment data while the security of guarantee explosion environment.
The technical solution realizing the utility model object is: a kind of protection type vehicle bottom explosion environment analogue means, comprise protection walls, the stationary platform be fixedly connected with protection walls bottom and be placed in the support adjustment mechanism of stationary platform bottom, described protection walls comprises the inner layer wall arranged with one heart successively from the inside to the outside, middle level wall and outer wall, described inner layer wall and middle level wall are up big and down small taper cone barrel, described outer wall is cylindrical drum, described inner layer wall and middle level wall are provided with multiple compact arranged bellmouth orifice, large outer little in described each bellmouth orifice, its central axis points to explosion center, foamed aluminium is adhesive with inside the wall of described middle level, foamed aluminium is adhesive with inside described outer wall.
The utility model compared with prior art, its remarkable advantage:
1, safety: the shock wave significantly being guided, absorb blast generation by three-layer protection wall and foamed aluminium structure, make blast analogue device peripheral environment from the impact of shock wave, trumpet-shaped pod apertures, effectively explosion wave is directed to skin, and the explosion wave of reflection is stoped at skin, ensure that the safety of testing crew well, make more easily to carry out in test among a small circle, efficiently solve motor vehicles explosive test place problem greatly, costly;
2, experimental data is accurate: structure is simple, and easy for installation, can be used for the explosive test of various protection type vehicle by the change of size, vehicle support mechanism can regulate bearing height easily, makes the control of tester to fried distance more accurate; Residing space belongs to semi-hermetic region, affects less by outside environmental elements, facilitates sensor to obtain high accuracy experiment data.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the vertical view of the utility model protection type vehicle bottom explosion environment analogue means.
Fig. 2 is A-A sectional view in Fig. 1, the inner structure of reflection the utility model protection type vehicle bottom explosion environment analogue means.
Fig. 3 is the partial enlarged drawing of support adjustment mechanism in Fig. 2.
In figure, 1 protection walls, 2 stationary platforms, 3 support adjustment mechanisms, 11 inner layer walls, 12 middle level walls, 13 outer walls, 111,121 bellmouth orifices, 122,132 foamed aluminiums, 30 supporting and regulating devices, 31 screw rods, 32 follower gears, 33 driving gears, 34 speed reduction units, 35 motors, 36 thrust bearings, 37 supporting seats.
Embodiment
As Fig. 1, shown in 2, the utility model protection type vehicle bottom explosion environment analogue means, comprise protection walls 1, the stationary platform 2 be fixedly connected with protection walls 1 bottom and be placed in the support adjustment mechanism 3 of stationary platform 2 bottom, described protection walls 1 comprises the inner layer wall 11 arranged with one heart successively from the inside to the outside, middle level wall 12 and outer wall 13, described inner layer wall 11 and middle level wall 12 are up big and down small taper cone barrel, described outer wall 13 is cylindrical drum, described inner layer wall 11 and middle level wall 12 are provided with multiple compact arranged bellmouth orifice 111, 121, described each bellmouth orifice 111, large outer little in 121, its central axis points to explosion center 0, foamed aluminium 122 is adhesive with inside described middle level wall 12, foamed aluminium 132 is adhesive with inside described outer wall 13.
Described supporting mechanism 3 comprises four supporting and regulating devices 30.
As shown in Figure 3, described supporting and regulating device 30 comprise with the plane perpendicular of described stationary platform 2 and the screw rod 31 be connected with stationary platform 2 threaded engagement, and the follower gear 32 that be fixedly connected with, the driving gear 33 that with described follower gear 32 engage coaxial with described screw rod 31, the speed reduction unit 34 that simultaneously engages with described driving gear 33 and motor 35.
