Technical field
It is more particularly to a kind of to be used for Hopkinson pressure bar reality the present invention relates to In Dynamic Testing of Materials research field
Test foil gauge stiffening device.
Background technology
In Hopkinson pressure bar experiment, trip rod collides with incident bar, compression stress wave can be produced, when in incident bar
When stress pulse reaches the contact surface with sample, a part is reflected, and back wave is formed in incident bar；Another part then passes through
Sample enters in transmission bar, forms transmitted wave.It is required to that resistance strain gage is installed on incident bar and transmission bar, quilt is changed by it
Position stress is surveyed, to record the pulse signal changed over time.Typically soldering connection is used between wire and foil gauge
Connected mode, solder main component is leypewter, and its weld strength is relatively low.It is fixed under this moment high-speed impact
Foil gauge on incident bar and transmission bar, if producing fracture between foil gauge and wire, can be surveyed number by shock loading
According to will be difficult to ensure that authenticity, therefore need the foil gauge frequently more renewed, it will cause the efficiency of experiment to substantially reduce.
The content of the invention
The invention provides one kind to be used for Hopkinson pressure bar experiment foil gauge stiffening device, can solve the problem that following some skills
Art problem：Due to during Hopkinson pressure bar use, as rod member can be severely affected in high-speed impact foil gauge
Load, if without corresponding safeguard measure, the weld between wire and foil gauge is easily broken.It is proposed by the invention
Device can effectively protect foil gauge, it is exempted from destruction under shock loading.Foil gauge stiffening sleeve can wrap completely
Whole strain chip architecture is wrapped up in, ventilating opening is offered thereon, send glue hole；M type sealing rings, Neng Goufang are included inside axial glue seal apparatus
Only liquid glue overflow device；Axial a total of two of glue seal apparatus, foil gauge is individually fixed in using threaded connection and reinforced
Axle sleeve both ends；Each axial glue seal apparatus is engaged with four tightening screws, completes whole device clamping and positioning.
The present invention uses following technical scheme.
Step 1：Foil gauge stiffening sleeve fully wrapped around can entirely strain chip architecture, and its diameter of bore size is more than suddenly
The size of Pu Jinsen pressure shafts, offer send glue hole thereon, liquid glue can be full of the gap between axle sleeve and bar, complete
To the cladding process of foil gauge.
Step 2：Ventilating opening is offered on foil gauge stiffening sleeve, realizes the accelerated solidification process to liquid glue.
Step 3：M type sealing rings are included inside axial glue seal apparatus, play the sealing function to whole device.
Step 4：Each axial glue seal apparatus is provided with screw thread, cooperates and connects with foil gauge stiffening sleeve.
Step 5：Each axial glue seal apparatus offers four screwed holes, is cooperated with four tightening screws, can be right
Whole device plays aligning effect, ensures the axiality between device and Hopkinson pressure bar so that glue can be uniformly filled in
Whole device.
The beneficial effect of the present invention compared with prior art.
1. existing foil gauge guard method and structure have certain safeguard function for foil gauge, it can be ensured
Destruction is exempted from, but its structure is not easy to separate with test specimen, the present invention uses resilient flexible fluid sealant, is filled out with good during liquid
Performance is stitched, there is good flexibility after the glue solidifies, it is corrosion-free to Hopkinson pressure bar and foil gauge stiffening device, dirty without infiltration
Dye, is easy to remove after the completion of experiment with commonsense method.
2. other foil gauge protection structures may produce extra pressure to foil gauge, experimental data is produced certain
Influence, can cause experiment value that there is larger deviation, the device that the present invention uses is uniform to the cladding area of foil gauge, therefore
Stress is relatively more uniform.
3. foil gauge stiffening device proposed by the invention can be reinforced effectively to foil gauge, greatly reduce
The replacement frequency of foil gauge, efficiency can be improved during actual experiment.
4. foil gauge stiffening device proposed by the invention is attached using thread connecting mode and clamping and positioning, M
Type sealing ring is positioned over inside axial glue seal apparatus, therefore treats that disassembly process is more convenient after the glue solidifies.
