摘要
使用Multiphysics分析软件,建立了半导体桥发火换能元的有限元仿真模型。重点研究A型、B型两种半导体桥发火换能元在直流激励条件下的安全性能和输出性能。对换能元高瞬发点火时的温度响应进行仿真分析,得出两种情况下换能元的温度分布云图,并利用红外热波无损检测技术进行温度检测。对比仿真结果进行分析,获取换能元结构、性能等数据,完善火工品换能元性能检测技术。结果表明,B型半导体桥换能元更符合火工品安全性和可靠性要求。
Multiphysics engineering analysis software is used to establish a finite element analysis model for micro transformer in semiconductive bridge. The safety and output performances of micro-transformers A( 15 μm × 60 μm) and B( 100 μm × 400 μm) are analyzed,and their temperature responses under the condition of high instantaneous ignition are simulated. Radial temperatures of two kinds of transformer are procured. The infrared nondestructive detecting technology is used to detect its temperature. The simulated results are analyzed to obtain the structure and performance data of transformers. The results show that B type micro transformer is more safe and reliable.
