冲击闭合器是某超低空地空导弹触发引信上的一个部件。它通过导弹碰目标时所获得的惯性力起作用。为了保证冲击闭合器作用可靠,我们在地面上用冲击试验机对它进行了模拟试验。为了叙述方便,先介绍它的构造和作用。 Impact Closure is an ultra low-altitude surface to air missile trigger fuze on a part. It works by the inertial force obtained when the missile touches the target. In order to ensure the impact closure device is reliable, we simulated it on the ground with an impact tester. In order to describe the convenience, first introduce its structure and function.
