Technical field
The present invention relates to a kind of environmental test method tested using snowmaking and environment test device, it is specific and
Speech, be related to it is a kind of will not cause ice matter change and can when needed using the snowmaking of requirement come suitably tested,
Utilize the environmental test method and environment test device of snowmaking.
Background technology
In the prior art, people utilize environmental test chamber, and the vehicle for the vehicle for completing production is positioned in the laboratory,
Various natural environments, meteorological condition are set later, and to collect, analyze the natural environment, meteorological condition generates vehicle
Influence data.
As an example, such as in environmental test room wind and snow is simulated using snowmaking, the wind and snow is made to blow to vehicle, from
And to caused by being mixed into snow in engine chamber failure problems, the ice formation issues such as freeze of foot's peripheral parts handle.
Therefore, environmental test chamber has wind-tunnel and wind and snow forming apparatus, wherein wind-tunnel has for configuring vehicle and making wind
Snow blows to the sufficient space of vehicle.
Wind and snow forming apparatus for example with：Ice machine manufactures flake ice；Ice crusher, the flake ice that ice machine is produced
It is broken into the ice pellets of specified particle size；Piping is used to that snowmaking will to be used as by the broken ice pellets obtained with specified particle size
It is transported in wind-tunnel；Nozzle is blowed, the top of piping is set to, for blowing snowmaking to the front of vehicle.
It, can by blowing wind and snow to vehicle in wind-tunnel using wind and snow forming apparatus using such environmental test chamber
Carry out the environmental test of simulating natural environment and meteorological condition.
However, the method due to preparing wind and snow, can cause following technical problem.
First, in the prior art, shape to be used for since before carrying out environmental test, previously fabricated environmental test is the desired amount of
At the snowmaking of wind and snow, and these snowmaking are stored, thus, if for example, broken ice pellets obtained is deposited as snowmaking
Storage, then the ice matter (state of snowmaking) of snowmaking can change, and lead to not implement experiment appropriate, alternatively, sometimes also
It can not can implement to test.
Specifically, it during storing snowmaking, is bonded together sometimes due to the change water on surface between ice pellets,
Cause ice pellets to become ice cube, can lead to not simulate actual wind and snow and experiment appropriate can not be carried out, or in transmission process
Middle ice pellets blocks in piping, it is difficult to convey ice pellets.When forming wind and snow using artificial snow slush, it is this to be particularly susceptible generation
Problem.
In addition, when manufacturing the snowmaking of requirement before the test is conducted, the process for manufacturing snowmaking is had in environment

Effectively utilize general environmental test chamber.
Second, it is difficult to during carrying out environmental test, be carried out in fact to being used to form the requirement of snowmaking of wind and snow
When adjust.
Especially, from when blowing the ice pellets blowed out in nozzle and being conveyed to vehicle with air-flow, pass through and change air-flow
Relative to the speed of stationary vehicle, situation when wind and snow is blowed to the vehicle just travelled at various speeds to simulate.At this point, due to
The change of air velocity makes the concentration of wind and snow independently change, and leads to not carry out experiment appropriate, thus, in order to make
The concentration of wind and snow maintains certain level, needs the blowing volume for changing wind and snow in real time according to the variation of air velocity.
Moreover, because front vehicles pass through on the accumulated snow on road so that the accumulated snow on road splashes and forms wind and snow
When, the concentration distribution of the wind and snow in the short transverse of vehicle concentration when closer apart from road is higher, therefore, to simulate in this way
Situation, it is necessary to change the concentration distribution of the wind and snow in the short transverse of vehicle, to need further wind and snow is blowed
Amount carries out subtle adjustment.In addition, the object of environmental test is not limited to vehicle, can also be the house as fixed object,
The various objects such as electric pole, at this point, in general, the concentration distribution of the wind and snow of nature is dense when closer apart from earth's surface

First manufacture and store a large amount of ice (snowmaking), and not making in site snowmaking when needed.
In contrast, a kind of artificial snow-maker is disclosed in patent document 2, laminar flake ice is manufactured by ice machine,
It is equipped with hopper in the lower section of the flake ice outlet of the ice machine, is equipped with ice crusher in the lower section of the hopper, which will be thin
Flake ice is broken or crushes to manufacture snowmaking, is equipped with pneumatic conveying band in the lower section of the ice crusher, which is used for
Snowmaking from ice crusher is transported to the snow pack institute such as training field.In patent document 2, a large amount of snowmaking is being needed
When, more ice machines and hopper corresponding with each ice machine are set, make the flake ice in each hopper fall on conveyer belt (such as
Spiral conveyor) on, so that flake ice is flocked together to fall in 1 ice crusher and is formed snowmaking, uses pneumatic conveying band will later
Snowmaking from dispenser is transported to training field, suitably dispenses snowmaking.
However, the artificial snow-maker is the device for supplying snowmaking for the training field etc. to skifield, in patent text
Offer will not publicly cause ice matter to change in 2 and can manufacture when needed requirement snowmaking thus allow for it is appropriate and
Environmental test method and environment test device efficiently testing, using snowmaking.
In addition, disclosing a kind of following technology in patent document 3：Snow is simulated using powdered substance, with scaled down
Building model is object, carries out the environmental test in relation to accumulated snow load.Specifically, multiple pipelines are configured along short transverse, it is more
A pipeline is spaced at intervals, and different for blowing the opening area of snow each other, blows and is used for into wind-tunnel from the pipeline

Rupture, can obtain laminar flake ice, can be to the evaporating temperature and/or water temperature of cooling medium and/or reamer in ice making
Rotating speed is adjusted, however but there are the following problems.
That is, 1 table-hinges blade ice machine can previously fabricated ice-making capacity be limited, when needing using a large amount of artificial
When snow carries out environmental test, need to use more table-hinges blade ice machines, if in addition, before the test is conducted, making manufacture by reamer
Ice sheet rupture after be stored in ice-making compartment as flake ice, compared with the case where being stored as the ice pellets after trash ice, draw
The possibility for playing ice qualitative change is smaller, but since flake ice may be bonded together, thus before proceeding by environmental test,
It needs to detach so that trash ice can be carried out the flake ice being bonded together, thus is more troublesome.
