The Simulation Study On Protective Technology Of Testing Instrument In The Explosion Environment

In the modern military and civil engineering,many structures often suffer fromexplosion wave, because explosion wave has characterized of high initial value, fast decay andshort duration that differ other dynamic loads,therefore, protective technology research ofstructures under explosion wave is very valuable in practice.The paper mainly discusses the research of dynamic response and buffer protection ofmissile-borne testing instrument in the explosion environment, and prove the validity of finiteelement program by the use of large FEM software ANSYS 10.0/LS-DYNA to do the 3Dnumerical simulation, and provide the reference for testing of analysis and design ofequipments protection technique.The thesis begins with the summarization of the demands and technique actuality in andabroad the country of simulation technique, analysis the formation and propagation course ofexplosion wave; and by the use of FEM software ANSYS/LS-DYNA to do the numericalsimulation for explosion course .And on this basis, the protection technique of testinginstrument is analysised and designed, use the ANSYS10.0/LS-DYNA to do the numericalsimulation to get the dynamical response data of the testing instrument for differentprotective structure and different protective material, and sum up the effectual protectivetechnique of testing instrument from the Data comparison analysis. And thereby improvingthe survival of equipment in the extreme environment, increasing the rate of recycling anddata-taking of test instrument .The protection technique this paper researches on is of great practicability, definitelyadvance and outstanding features thus can improve the testing capability of weapon systemtrustfully and effectively.
