摘要
针对弹-引-机构弹道环境信息及响应传递规律不明确的问题,提出一种高速旋转弹丸引信全链路环境信息测试方法.在弹体头部和尾部分别安装测试系统,测量在弹丸发射和飞行过程中弹体、引信、引信机构形成的全链路弹道环境.炮射试验证明,膛内阶段弹体过载通过螺纹传递到引信体,过载峰值增大16.45％.在出炮口半约束期阶段引信径向过载比膛内过载分别增大8.1倍、2.8倍,引信机构过载以低频分量为主,含有少量频率为262.5 Hz的信号,周期约4 ms.
Abstract
Aiming at the problem of unclear information and response transmission laws in the trajectory envi-ronment of the projectile guidance mechanism,this paper established a testing method for the full link environ-mental information of high-speed rotating projectile fuze.By installing testing systems at the head and tail of the projectile,it could measure the full trajectory environment formed by the projectile-fuze-mechanism during launch and flight process.Gunfire tests showed that during the bore stage,the acceleration of the projectile is transmitted to the fuse body through threads,and the peak acceleration value increases by 16.45％.During the half constraint period at the muzzle,the radial acceleration of the fuze significantly increased comparing with the acceleration in the bore,increasing by 8.1 and 2.8 times respectively.The acceleration of the fuze mechanism was mainly composed of low-frequency components,containing a small amount of signal with a frequency of 262.5 Hz,with a period of about 4 ms.
