Explosive bolt is one of separation device that uses high explosive charge, and is separated by pressure formed by an explosion and the resulting shock waves. Explosive bolt having such a mechanism would have to be designed to minimize shock and debris formation generated during separation. In this study, separation tests were carried out wi th distance as variable for restraining the explosive bolt (Air Gap). Bolt release and its separating shape with variation of air gap is observed, and we used accelerometer to measure the shock wave transmitted through a bound object. In addition, separation behavior of explosive bolt is analyzed usi ng ANSYS AUOTODYN program. By comparing the results of previously performed experiments and a nalysis, we could confirm the effects of air gap to the release behavior of explosive bolt, and decid e optimum constraining environment for specific separation bolts.               .             .
