碩士 / 大葉大學 / 機械與自動化工程學系 / 107 / Military naval vessels and general naval vessels are different from the warships have the ability to combat, it is necessary to face the etonation of fighting environment, in order to ensure that the warships withstand underwater detonation equipment can continue normal operation, its resistance to detonation capacity requirements , The Navy’s shock test standard MIL-STD-901D requires that newly designed equipment must be tested and verified before being loaded to ensure that Class A and Class B
equipment meets the requirements for knocking. And the Dynamic Design Analysis Method (DDAM) is the U.S. Navy’s specified analytical method of qualifying non testable equipment and supporting structures to withstand the effects of shock. After the 1970s, the US military's auditing tandards for knock values were based on Keel Shock Factor (KSF) and Hull Shock Factor (HSF) as damage blasting systems. The equipment, system, and pedestal on the ship can be informed of the explosion of the experimental testing or ship tests. but the shock test is time-consuming,laborious
and spend money. And the finite element modeling and simulation can provide a viable, cost effective alternative to shock tests.
In this study, two methods, Acoustic-Structure Coupling Method (ASC) and Dynamic Design Analysis Method (DDAM) were applied to Acoustic-Structure Coupling Method and Dynamic Design Analysis for submarine torpedo tubes subjected to 300 metre water pressure and underwater explosion. Method. The environment was set up with the Acoustic-Structure Coupling Method MIL-S-901D Heavy Weight Shock Test for knock analysis. Using the Acoustic-Structure Coupling Method results, the torpedo tube was subjected to underwater explosion under water pressure of 300 meters under water, and the max vos Mises was 365.5MPa. Using the Acoustic-Structure Coupling
Method MIL-S-901D Heavy Weight Shock Test for knock analysis results, the max vos Mises was 495MPa.Using the Dynamic Design Analysis Method results, the torpedo tube was subjected to underwater explosion under water pressure of 300 meters under water, and the max vos Mises was 413.8MPa. The results of the three analyses show that the maximum stress value of the torpedo tube does not reach the stress, so the torpedo tube will not cause permanent deformation and damage, and can continue to fight after the underwater explosion
