Non-nuclear Explosion, The Magnetic Flux Compression Generator Numerical Simulation And Experimental Study

Starting with the basic principle of non-nuclear explosive magnetic flux compressiongenerator, this paper synthesizes forefathers' mentality of designing and chooses the helicalmagnetic flux compression generator as the research object, builds up its equivalent circuitmodel. Using the method of ALE arithmetic of LS-DYNA to simulation the armatureexpansion process of the magnetic flux compression generators with diffrient armaturematerial, diffrient armature dimension and diffrient stator dimension, the results ofsimulation present the picture of each expansion process of armature, the expansion angle,the expansion velocity and device operating time; Based on results. of numerical simulationthe armature expansion process, dynamic inductance and dynamic resistance models arebuilt; It also discusses the relationship of the structure parameter in the operating course ofnon-nuclear magnetic flux compression generator, the exploding parameter, the operatingtime, the circuit parameter and the pulse current, pulse energy, pulse voltage and pulsepower. Finally, based on the theoretic, it produces the entity model, and verifies thecorrectness of the theory through the test.The problem that this paper mainly solves is: Firstly, it sets up the equivalent circuitmodel of explosive magnetic flux compression generator. Secondly, Using the method ofALE arithmetic of LS-DYNA to simulation each armature expansion process and processof contact with stator, the results of simulation present the picture of each expansionprocess of the armature, the expansion angle, the expansion velocity and device operatingtime. Thirdly, on the basis of results of numerical simulation the armature expansionprocess, using such relevant knowledge as explosion dynamics and electromagnetism etc.,dynamic inductance and dynamic resistance models are built. Fourthly, it utilizes numericalsimulation of structure parameter to find out the impact on produced strong pulse current,pulse energy, pulse voltage and pulse power of every parameter, thus we can control strongimpulse current, impulse energy, impulse voltage and impulse power needed throughchanging the relevant parameter. Fourthly, it verifies the correctness of the theory throughthe test.
