Abstract

In order to improve the performance of magnetic flux compression generator, a cylinder-conical generatoris designed, and the dynamic response characteristic of armature in the generator is studied. The clustering algorithm and text mining technology are used to develop secondarily LS-DYNA software. The code which makes the node failure and separates the finite element mesh is compiled, and a simulation model is established to simulate dynamic expansion and fracture process of generator. Expansion angle, radial expansion velocity and fracture radius of armature are presented. The calculated results show that the proposed model can be used to predict the expansion and fracture process of armature, and the simulated expansion angle, radial expansion velocity and fracture radius of armature are close to the theoretical values. The method can be used for the design of the magnetic flux compression generator, optimizing the structure of generator and improving its output performance.Key
