触发引信在导弹上的安装位置必须满足刚性连接、振动放大小和可靠传递过载等要求。利用Abaqus软件对某装配体进行模态分析和随机振动分析，获取其固有频率和在给定振动量级下的振动量级图谱。仿真结果表明触发引信安装位置正好处于装配体振动放大最严重的区域。进一步的振动试验结果显示触发引信安装位置的确存在振动放大，证实了仿真分析结果。最后，根据仿真结果和试验数据，对触发引信的安装位置进行了重新设计，使其更合理。

In the missile impact fuse’s mount-ing position must meet the rigid connection, small vibra-tion amplification and reliable transmission of overload and other requirements. Using Abaqus software to calcu-late modal analysis and random vibration analysis of one assembly structure, obtains its natural frequency and the vibration magnitude spectrum in a given vibration magni-tude. The simulation results show that the mounting posi-tion of impact fuse just laid in the most serious vibration amplification regions of the assembly. The vibration test results show impact fuse mounting position exactly exists vibration ampliifcation, conifrmed the results of simulation analysis. Finally, according to the simulation results and the experimental data, the impact fuse mounting position was redesigned, to make it more reasonable.
