摘要

To investigate the dynamic mechanical performance of Nd₂Fe₁₄B hard ferromagnetic under shock wave loading, the plane shock wave loading experimental device was designed and the shock loading experiments were conducted. The pressures of shock wave in Nd₂Fe₁₄B ferromagnetic were measured by a set of Manganin pressure gauge. The calculating model of Nd₂Fe₁₄B ferromagnetic under shock wave loading was established. The process of the shock wave loading Nd₂Fe₁₄B magnets was simulated. Calculated results were consistent with experimental data. The attenuation law of shock wave pressure in Nd₂Fe₁₄B was analyzed and the first order exponential attenuation formula used to describe the shock waves propagation in Nd₂Fe₁₄B ferromagnetic was given.
