Description
Technical field
This utility model relates to explosion mechanics modeling techniques field, can clamp examination particularly in one blast or impact test
Part, gripper sleeve with stress wave transmission bed course.
Background technology
Explosion mechanics model test is the important means of explosion mechanics research, and it is based on the theory of similarity in mechanics and dynamics of explosion
Ultimate principle, copies prototype test operating mode and sets up scaled model according to certain similar proportion and carry out test.Model test is selected
Suitable ratio chi, similar quick-fried source, analog material, make the subjects similar to prototype, reproduces the actual working state of prototype,
Finally according to criterion of similarity repairing experiment result, calculate the virtual condition of prototype.First the science of explosion mechanics model test takes
Certainly having identical physical change process in model and prototype, next be also satisfied the condition of similarity of physical phenomenon characteristic parameter, with
And similar boundary condition.This just proposes requirement to the boundary condition of test specimen in model test.
In prototype test, quick-fried source is generally embedded in underground, and in addition to resistance in the direction of the smallest line, other all directions are all by Jie of infinite thickness
Matter is wrapped up, and is therefore nonreflecting boundary condition；In model test, owing to the size of test specimen is limited, stress wave arrives test specimen border
After necessarily lead to stress concentration, interference test result.
After nonreflecting boundary condition refers to that stress wave arrives border, echo will not be produced.But for the test specimen of finite size,
When stress wave arrives material boundary, echo will necessarily be produced, thus in order to eliminate the impact of this echo, can pass through
Following approach realizes: increase sample dimensions so that when stress wave arrives material boundary, peak stress is sufficiently small, from without making
Become material, at boundary, irreversible deformation occurs.But this way so that the size of test specimen is the biggest, it tends to be difficult to realize
The molding of test specimen and molding；It addition, increase material usage, curing time and cost of transportation.
Utility model content
This utility model solves and explodes or impact stress concentration interference factor in similar test under finite size and be difficult to eliminate and try
Part is difficult to carrying and flimsy problem, it is provided that a kind of simple in construction, easy and simple to handle, easily installs, does not easily cause specimen fails
The gripper sleeve with stress wave transmission bed course.
In order to solve above-mentioned technical problem, the technical solution of the utility model is:. a kind of retaining sleeve with stress wave transmission bed course
Cylinder, including body, described body is made up of lateral Displacement outer rigid housing and elastic endergonic bed course, described elastic endergonic bed course
It is embedded in lateral Displacement outer rigid housing.
Gripper sleeve is embedded by the elastic endergonic bed course made by elastic endergonic material, will explode or test specimen parcel used by impact test
Get up, form a boundary condition with transmission stress wave function.
Lateral Displacement outer rigid housing is made up of rigid material, has lateral Displacement and the function of clamping internal material.
As preferably, described lateral Displacement outer rigid housing is connected in sequence by connector by several outer rigid housing unit.
Simple in construction, installs and uses process very convenient.
As preferably, described outer rigid housing unit both sides are equipped with connection hole, are used for arranging connector.
As preferably, described connection hole is two, setting symmetrical above and below.Make lateral Displacement outer rigid housing stability more preferable.
As preferably, the outer wall of described lateral Displacement outer rigid housing is provided with handle.It is easy to carrying or suspention test specimen.
As preferably, described gripper sleeve is cylindric.
Using technique scheme, elastic endergonic bed course is embedded between lateral Displacement outer rigid housing and test specimen by this utility model,
The stress wave that energy-absorbing is come by test specimen internal delivery, it is achieved nonreflecting boundary condition；Simple in construction, easy and simple to handle, easily install and
Dismounting, recycling rate of waterused is high, does not easily cause specimen fails, solves to explode under finite size or impact to reflect in similar test and draws
Stretch the problem that wave interference factor is difficult to eliminate, solve test specimen simultaneously and be difficult to carrying and flimsy problem.

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.At this it should be noted that for this
The explanation of a little embodiments is adapted to assist in and understands this utility model, but is not intended that restriction of the present utility model.Additionally, below
Just can be mutual as long as technical characteristic involved in described each embodiment of this utility model does not constitutes conflict each other
Combination.
In this utility model, elastic endergonic bed course is made up of elastic endergonic material, such as: polyurethane, polyurathamc, rubber,
Bipeltate, concrete material parameter determines according to the actual requirements, by factory's customization processing or directly can buy in market, then cut
It is assembled into predetermined configuration.Lateral Displacement outer rigid housing is by commercially available large diameter steel pipe, through cutting, again assembled molding；Also can be by
Commercially available 2～3mm steel plate volume be bundled into type.
Such as figure, a kind of gripper sleeve with stress wave transmission bed course, including body, by lateral Displacement outer rigid housing 1 and elasticity
Energy-absorbing bed course 2 forms, and elastic endergonic bed course 2 is embedded in lateral Displacement outer rigid housing 1.Lateral Displacement outer rigid housing 1 is by some
Individual outer rigid housing unit 3 is connected in sequence by connector 4, and outer rigid housing unit 3 both sides are equipped with connection hole 5,
Connecting hole 5 is two, and setting symmetrical above and below is used for arranging connector 4, and the outer wall of lateral Displacement outer rigid housing 1 is provided with
Handle 6, convenient carrying or suspention test specimen.
In this utility model, after the test specimen demoulding in blast or impact test, elastic endergonic bed course 2 is wrapped in test specimen peripheral,
Then with lateral Displacement outer rigid housing 1, elastic endergonic bed course 2 is wrapped up, and with connector 4 by lateral Displacement outer rigid housing
1 each parts connect and fixing, form entirety and about bind round power.So, a sleeve with transmission stress wave function is just defined.
After blast or impact test complete, first connector 4 is taken off, then takes off each unit of lateral Displacement outer rigid housing 1,
Finally elastic endergonic bed course 2 can be reclaimed, thus whole device can be reused.
This utility model apparatus structure is simple, easy and simple to handle, easily mounts and dismounts, and recycling rate of waterused is high, does not easily cause sample and damages
Bad, solve and explode or impact stress concentration interference factor in similar test under finite size and be difficult to the problem eliminated, solve simultaneously
Test specimen of having determined is difficult to carrying and flimsy problem.
Above in association with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to described reality
Execute mode.For a person skilled in the art, in the case of without departing from this utility model principle and spirit, real to these
The mode of executing carries out multiple change, revises, replaces and modification, still falls within protection domain of the present utility model.
