Description
Technical field
The present invention relates to gas big gun experiment field, specially the gas big gun based on the interference of light and multi-stage LED illumination is to target system.
Background technology
In the Experiments of Machanics of impact gas big gun, such as Fig. 1, by the way of by drive of high-pressure gas bullet, flies in bullet
Sample is loaded after crossing gun tube, the projectile impact after high-speed flight is fixed on the target surface in target chamber, in experimentation,
Film flying whether can parallel central collision target surface experimental result is affected big, especially rise to measuring stress wave during low velocity impact
Have a strong impact on during the time width in forward position.The existing common practice for solving this problem is solid with one before the experiments
Metal lining bar be placed in gun tube and carry out " to target ".
In the experiment of gas big gun now, carried out by the way of setting-out rod in gun tube to target, as shown in Figure 2.Using figure three this
The mode of kind adjusts the middle that lining bar end face is placed in target disc, additionally, ensure that using Fig. 4 target disc is parallel with the right-hand member of lining bar, with
Sample is using visually observing mode.In fig. 2, the cylinder lining bar that dark parts are done for solid metal, simulates film flying travel path,
The right grey parts are the target disc for installing sample, are the target platform for installing target disc below target disc.Meat is adopted before testing now
Eye observation lining bar (middle black circle) position, such as Fig. 3.
In the diagram, the parallel degree of target disc and lining bar right side is manually gesticulated using edge of a knife chi, can only typically ensure one
The depth of parallelism in direction.
The shortcoming of the technology has following：
(1) lining bar for being done using solid metal is heavy, and operation is painstaking, it is contemplated that lining bar and gun tube internal diameter are fitted close, behaviour
Make often to take for a long time, green hand can spend more than one hours, and due to target chamber limited space, the operating time is longer, is more difficult to be aligned.
(2) visually observe to target, error is larger, when especially observing stress wave rising front in low speed experiment, to target not
The error that standard is brought is difficult to ignore.It cannot be guaranteed that same experimental conditions produce same experimental result.If the lining bar right side and sample
Not parallel, error is up to the millimeter order of magnitude.
(3) as target platform is that bulk metal is made, heavy, painstaking to target operation, easily produce between wad cutter and blasthole
Dislocation, in shock recovery experiment, when sample in cross section size and suitable film flying, is unable to reach to the impact of recovery sample and symmetrically touches
The effect that hits.
