高g值加速度冲击试验技术研究

摘 要：根据弹体高速侵彻硬目标过程中加速度测试的特点，研制了高g值冲击试验装置。它由一级空气炮、加速度存储测试装置、炮弹、反射式激光测速仪和激光多普勒测速仪等组成，并在该冲击试验装置上进行了弹载加速度存储测试装置的高g值冲击试验。采用泡沫铝缓冲件对记录电路模块进行缓冲保护，利用光栅作为合作目标，由两套激光多普勒测速仪同时记录冲击过程中测试装置外壳和电路模块的激光频移信号， 处理可得到二者的加速度——时间曲线，比较了泡沫铝的高g值缓冲效果。

Acceleraton shock test technology with higher values of G

According to the characteristic of acceleration test in processes of projectile penetration into a hard target with higher velocity,a kind of novel shock test equipment with higher values of g was developed.It was composed of one-stage air gun,acceleration storage test and measurement equipment,shell,reflect type Laser velocimeter and Laser Doppler velocimeter.Moreover the shock test with higher values of g on the onboard acceleration storage test and measurement equipment was conducted with the above test ...
