摘要

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。

Abstract

Abstract: According to the characteristic of acceleration test in the processes course of projectile penetration into hard target with high velocity, a kind of novel high g shock experiment equipment have been developed by us. It is composed of one-stage air gun, acceleration storage test and measurement equipment, shell, reflect type Laser velocimeter and Laser Doppler velocimeter, moreover the high g shock experiment on Onboard acceleration storage test and measurement equipment is carried out through with above experiment equipment. The foamed aluminum buffer cushion is employed used to protect the memory circuit modulus, and the grating is utilized as cooperative aim target, so Laser frequency shifting signal from external shell of the test equipment and the circuit modulus in high shock processes course are recorded synchronously by two sets of Laser Doppler velocimeters. Their acceleration –time curve are acquired and the buffer cushion effect are compared.
