Description
Technical field
The present invention relates to a kind of coaxial shock wave electric probe and method for making thereof, more particularly, relate to a kind of novel self-short-circuit type coaxial shock wave electric probe and method for making thereof that is applicable to shock velocity in the test liquid material.
Background technology
For simulation material is experiencing High Temperature High Pressure, the characteristic under the extreme conditions such as cryogenic high pressure and low-temp low-pressure, shock wave high velocity impact-measuring technique commonly used is carried out dynamic load to material, and the original state of material often is a liquid under these extreme conditions.Solid material can accurately calculate with crystal model, gas material can be used ideal gas model accurate description, but the structure of fluent material neither resembles solid material and does not resemble gas material again, thus be difficult to calculate with existing theoretical model, can only be with half classics or experimental formula approximate description.Based on this, so need the development coaxial shock wave electric probe, the ballistic motion speed that produces when being used for that fluent material carried out dynamic load is measured.This technology is particular importance in the research of manned spacecraft is used now, similarly uses to also have in torpedo, der Amphibien-Tank and naval vessel plate armour and resist the ability evaluation of missile impact and the assessment of practical function etc. in actual combat; Rocket ship is under extreme conditions resisted the ability of space trash bump in-flight; And the high velocity impact test carried out of the security of travelling for means of transports such as check automobile, train, naval vessels.Principal ingredient such as organization of human body is a water, the research fluent material just comprises the degree of human body damaged under thump in the performance change under the shock wave effect, tests and studies so all will implant the liquid measurand with this type of electric probe when determining the safety index of the Modern High-Speed vehicles.
Shock wave electric probe is to utilize detonation technology and impact compress technical research fluent material in High Temperature High Pressure, rerum natura under the extreme condition such as cryogenic high pressure and low-temp low-pressure, detonation is to utilize explosive strong shock wave compression sample material, impact compress is to utilize gas big gun technical modelling detonation wave, drive film flying collision specimen material, because speed is too fast, up to 7km/s, therefore, can't directly measure the rerum natura of fluent material by compression the time, can only measure indirectly in the velocity variations that causes by fluent material itself by measuring shock waves.According to the shock velocity in the fluent material that records, the time interval of promptly measuring the fixed length path on the path that shock wave passes through calculates shock velocity then, can obtain the high pressure property information of fluent material in conjunction with Hugoniot relation and the law of thermodynamics.The precision that needs nanosecond order during by measuring shock waves speed research fluent material characteristic, if deviation ± 1 nanosecond, material behavior estimate can deviation up to 10%.So big error is unallowable at conventional weapon such as tactical missile, rocket etc., obviously, the measuring accuracy of shock velocity has determined the correctness and the integrality of result of study, and shock wave electric probe is the principal element of decision shock velocity measuring accuracy.
