Quasi-Static Assessment of Response to Slamming Impact on Free Fall Lifeboats

摘要: Design against impact loads (slamming) can be challenging and time consuming involve complex calculations. Application of simplified, quasi-static calculation approaches will make the design process much easier. In this paper, such simplified methods are discussed using free fall lifeboats as a case. Results from non-linear FE-analysis show that response is due to large deformations. The pressure then mainly carried by membrane stress dynamic small. A beam theory approach for hand established. As model most realistic, it recommended used in an initial assessment. Although results on conservative side, simple calculations including geometry predict maximum strain. Linear also investigated. However, these should with more rigid structures stiffened steel aluminium panels.
