현재의 많은 유도무기들은 발사관에 장착되어 보관 및 이동되다가 필요시 발사된다. 발사관이란 유도탄 즉 미사일등이 외부환경에 노출되지 않도록 유도탄을 둘러싸고 있는 일종의 케이스이며 또한 유도탄 발사시 가이드 역할을 동시에 수행한다. 유도탄과 발사관을 연결하는 방법으로 흔히 사용되는 것으로 탄고정장치를 사용하는데 대표적인 파이로 부품이 폭발볼트이다. 폭발볼트는 화약의 폭발력에 의해 볼트몸체가 절개됨으로써 볼트에 의해 결합되고 있던 부분이 분리된다. 하지만 기존의 폭발볼트는 분리시 파편, 화염 및 pyro-shock이라는 악작용을 수반하므로 사용상 제한을 가지고 있다 . 이와 같은 문제점을 해결하기 위하여 압력카트리지에서 발생하는 압력을 분리력으로 사용할 수 있는 분리장치 즉 볼타입 볼트를 개발하게 되었다. 본 연구에서는 볼타입볼트의 분리현상을 분석하여 분리볼트의 분리성능 안전율을 정량적으로 제시하였다. Most of the guided weapons have been kept and transferred at the launching tube and fired in case of necessity in these day. Launching tube is a kind of case to protect the guided weapons from external environments and conducted as a guide when they are fired. When we attached the guided weapons to launching tube we usually has used explosive bolt. Explosive bolts have been used explosives when they had to be separated. But when they are separated there are some bad effects; a flame, fragments and pyro-shock. Because of these bad effects there are many restriction to use bolt as joining devices to precision guided weapons. To solve these problems, it has been invented ball type bolt. The present work was represented quantitively the margin of separation safty and separation mechanism in ball type bolt to analyse the dynamic separation test. Unlike explosive bolt, ball type bolt is separated without a flame, fragments and pyro-shock. And it also has a good mechanical properties as much as those of explosive bolt.

Launching tube is a kind of case to protect the guided weapons from external environments and conducted as a guide when they are fired. The guided weapons have been firmly kept at the launching tube and transferred, and would be separated at the required time when they are fired To meet the aim, it has been used explosive bolts which are reliable and efficient mechanical fastening devices having the special feature of a built-in release. The disadvantage of explosive bolt lies in that it is based on the high explosive effect of a pyrotechnic charge. When the explosive bolt is ignited, there are some bad effects; a flame, fragments and pyro-shock. Because of these bad effects there are many restriction to use bolt as joining devices to precision guided weapons. To solve these problems, the aim of the present work is to invent the ball-type separation bolt which is a pyrotechnically releasable mechanical linking device for two mechanical elements that does not suffer from such drawbacks. A standard pressure cartridge can moreover be easily integrated inside the device according to the present work and this with no modification to its structure. The present work was represented quantitatively the margin of separation safety and analysed separation mechanism in ball type separating bolt to perform the dynamic separation test.
