Under, therefore, understanding material mechanical response feature under ultra-high temperature condition just becomes the study hotspot of association area.
At present, for Hopkinson superhigh temperature dynamic experiment, mainly there are two technical barriers:
The acquisition of hyperthermal environments on first, Hopkinson bar.Hopkinson bar to realize hyperthermal environments, just
Set of complementary must be had to be applicable to the superhigh temperature heating system of Hopkinson bar.
Second, the clamping of sample under superhigh temperature, owing to sample to be carried out superhigh temperature heating, and incident bar to be ensured and
Transmission bar is not heated to be damaged, and therefore to design a specimen holder and realize.
Li Yulong etc. are when realizing the experiment of high temperature dynamic load, and the heater of employing is the heating of ring-type controllable direct current power supply
Stove (Li Yulong, Suo Tao, Guo Weiguo, Hu Rui, Li Jinshan, Fu Hengzhi. determine material dynamic property under high temperature high strain-rate
Hopkinson lever system [J]. explode and impact, 2005,06:487-492.).Its thickness is 30mm, and inner via hole is a diameter of
35mm, heating wire is distributed in inner hole wall, and the heat-insulation tile and asbestos with customization is isolated with outer furnace shell.In-furnace temperature is by a closed loop
Controller controls electricity, and maximum temperature is up to 1000 DEG C.And for the material of aerospace field, its Service Environment often can reach
1600℃；Cyclic furnace is provided without good Insulation, and temperature loss is relatively big, and the efficiency of heating surface is low；For MATERIALS ' DYNAMIC power
Learning performance, generally requiring understanding sample destruction situation in loading procedure, so generally using ultra-high-speed photographic machine to sample
Taking pictures, cyclic furnace cannot meet requirement of taking pictures；For material Mechanics Performance Testing under hyperthermal environments, often
Relate to atmosphere of inert gases, and cyclic furnace used herein substantially can not reach these requirements.In sum, used herein
It is not enough to there are many places in cyclic furnace.
Summary of the invention
In order to overcome attainable experimental temperature present in prior art too low, poor thermal insulation property in heating process,
Protection in Hopkinson bar heating process and sample clamping problem in heating process, the present invention proposes a kind of base
Heating furnace and specimen holder in Hopkinson bar.
The present invention includes body of heater, watch window, heat-insulation layer, heating element heater and ceramic temperature sensor, it is characterised in that protect
Temperature layer is pasted onto the inner surface of body of heater.A side surface at described body of heater has the watch window of sandwich structure；With described
Two side surfaces of the body of heater that watch window is adjacent have incident bar passage and transmission bar passage, and described incident bar leads to
Road and transmission bar passage are concentric.The side surface of the body of heater corresponding with described watch window has body of heater back pullout (BPO), opens in the rear
The through hole for being installed into trachea is had on door.This body of heater back pullout (BPO) inner surface is pasted with heat-insulation layer；Described upper cover is arranged on this
The upper surface of body of heater, covers useful in the through hole installing exhaustor on this.Furnace chamber is defined in body of heater.Pottery temperature sensing
Device is embedded in the top of furnace chamber.Four molybdenum silicide heating elements are distributed in four side surfaces in described furnace chamber, and are inlaid in each side
The insulation layer surface on surface.
Described through hole for installing exhaustor and all through with furnace chamber for being installed into the through hole of trachea.
The profile of described molybdenum silicide heating elements is " u "-shaped.
Described heating furnace is along a length of 305mm in bar direction, and thickness is 210mm, a height of 280mm.The size of described furnace chamber
For 70mm × 70mm × 70mm.The size of described watch window is 80mm × 80mm.
The specimen holder that the present invention proposes uses cross section to be that semicircular alumina ceramic tube is made.Interior the half of this fixture
Footpath is respectively slightly larger than outer radius and the outer radius of transmission bar of the incident bar in described Hopkinson bar.
The present invention, with tradition Hopkinson lever system as standard, designs one between incident bar and transmission bar and independently adds
Hot stove and supporting specimen holder thereof.
The heating furnace entirety that the present invention proposes uses totally-enclosed design, and temperature range is controlled room temperature～1600 DEG C, internal
For furnace chamber, furnace chamber four wall is surrounded by heating element heater molybdenum disilicide, and body of heater remainder is by filled thermal insulation materials.Body of heater front is for seeing
Examining window, there is the through perforate for incident bar and transmission bar at body of heater two ends.Owing to needing to prevent sample in heating process
Oxidation, need to fill the protective gas such as nitrogen, be provided with air inlet pipe at the body of heater back side and top and gas outlet is passed through furnace chamber, with
Just protective gas, air-out it are passed through, it is achieved oxygen-free environment or be passed through hot and humid gas, it is achieved hygrothermal environment.It is arranged on body of heater
Exhaustor different protection gas can be passed in heating furnace in experimentation from air inlet pipe, make heating furnace to be formed not
Same atmosphere.When the protection gas (such as argon) being passed through, when density is more than air, from heating furnace gas introduced below, top
As air vent；When the protection gas (such as nitrogen) being passed through, when density is less than air, being passed through gas above heating furnace, lower section is led
Trachea air-out, it is achieved the oxygen-free environment in sample loading procedure.
