| 摘 要： | 在充分调研国内外SHTB装置的基础上,以较小的费用建成了一套摆锤式间接杆-杆型SHTB装置.动力装置为改造后的摆锤式冲击试样机,摆锤撞击速度为5m/s(不可调节),能量为300J.入射脉冲产生的关键技术为:通过金属短杆(材料为LY12cz)连接掩块与入射杆,摆锤撞击撞块,使短杆由弹性变形快速过渡到塑性变形直至断裂,入射...

| Abstract: | On the basis of the fully investigating SHTB apparatus at home and abroad,the pendulum type indirect bar-bar SHTB apparatus has been developed with the low cost.The powerplant is constituted by a transformed pendulum machine,the key technologies of generating incident square waves.The pendulum's unadjusted velocity is 5m/s,and the energy is 300J.The impacting block and incident bar are connected by a short metal bar whose material is LY12cz.The short metal bar transits fast from the elastic deformation to t... |
