摘要 为了研究在高加速度冲击过载条件下半导体桥(SCB)火工品受力损伤情况,采用分离式Hopkinson压杆对SCB火工品模拟样品进行了过载实验,并用有限元分析软件ANSYS/AUTODYN对SCB火工品的力学响应过程进行了仿真分析计算。研究结果表明,在高加速度冲击过载条件下,SCB火工品结构的薄弱部位在输出端的收口处,应对壳体采取加固措施以提高抗过载性能。 In order to study the damage of semiconductor bridge (SCB) initiator under high overload condition, the overload tests for simulated SCB initiator were carried out with split Hopkinson pressure bar. The numerical calculation was carried out by ANSYS/AUTODYN to analyze the mechanical response of SCB initiator. The results showed that, the weak part of SCB initiator is the crimping part of output end under high overload condition, the shell should be enhanced to improve anti-overload property of SCB.
