  • 文件描述:LS-DYNA软件水下爆炸模拟


Surface ship shock trials have been conducted in many countries for shock qualification of ship integrity, systems and subsystems. The ship shock trial identifies design and construction deficiencies that have a negative impact on ship and crew survivability. It also validates shock hardening criteria and performance. However, ship shock trials are costly. As a possible alternative, numerical modeling and simulation may provide viable information to look into
the details of dynamic characteristics of ship including component and sub-component level. Ship shock analyses were conducted using finite element based coupled ship and fluid model. Three-dimensional ship shock modeling and simulation has been performed and the predicted results were compared with ship shock test data. Surface ship shock analysis approach is presented and the important parameters are discussed.
