碩士 / 大葉大學 / 機械與自動化工程學系 / 105 / Currently hovercraft has been widely developed in the world and was divided into 2 main types: Air cushion vehicle (ACV) and sidewall hovercraft. The development of ACV of mainland China focuses on improving shipping capacity and performance of amphibious vessel in which the ship could be subjected to external effects such as tides, water depth, mine barriers, obstacles and landing slope or impact of coastal seafloor sediment. Therefore it has rapidly become a great military with a lot of transport equipment. The sidewall hovercraft with features of handling negative situation and directional stability, it is suitable for transporting large vessels.
Mainland China has early developed transports and landing hovercraft used in order to meet requirements of the military strategic principle in new tendency such as improving the landing hovercraft and accelerating research of offshore operations. Therefore, the concept of defensing the Taiwan Strait is necessary more than ever, the study of response of hovercraft structures subjected to underwater explosion caused by the detonation wave, bubble pulse, high-speed jet stream and the water column has conducted in this study.
The impact of high-speed jet on hovercraft is an attractive research area; there is a need for developing simulation tools for predicting the dynamic response of hovercraft body structure under high-speed impact and impingement of water jet. Considering this industrial need, incorporating a finite element model and CEL (Couple Eulerian- Lagrangian) method in ABAQUS software has been introducing. The syngene block has a maximum von-Mises stress of 346.6 Mpa compared with other obstructions so that it has a better hysteresis effect has been observed in this simulation. The dynamic response at high-speed jet impact is maximized at the point B of observation point von Mises Stress 393MPa of its acceleration G value of 8.35 (G), which analysis that water jet impact will produce the largest von Mises stress, and acceleration G value. Using this, proposals are suggested for designing hull structure and Gas Carrier Ship Construction.
