Title:
電磁誘導型ホプキンソン引張・圧縮棒ローディング装置及び実験方法
Document Type and Number:
Japanese Patent JP6840390
Kind Code:
B2
Abstract:
An electromagnetic induction type Hopkinson pressure/tension bar loading device and experiment method therefor. A positive electrode output line of the output of a capacitive charger is connected with a positive electrode line of a loading gun, and a negative electrode output line of the output of a capacitive charger is connected with a negative electrode line of the loading gun. The present invention not only can generate compression stress waves but also can generate tension stress waves through the electromagnetic induction principle, and is applied to the loading of a Hopkinson tension bar and a pressure bar. Thus, the loading systems for a Hopkinson tension bar and a pressure bar can simultaneously achieve the strain rate and strain range, which the traditional split Hopkinson bar experiment cannot reach, on the same device, so that the Hopkinson bar experiment technology is standardized, and the experiment devices for a tension bar and a pressure bar are integrated, thereby reducing complexity and floor space of equipment.
