摘要

本研究的目的是通过先进的有限元分析方法分析游艇的整体结构强度。为此，我们开发并使用了一个用户 FEMAP API 脚本，用于在平静水域、下陷波浪和迂回波浪条件下平衡有限元分析船舶模型，以适应不同的波浪设计高度，最大高度可达 6.5 米。通过屈服应力和屈曲标准对有限元强度进行评估。

On advanced global strength analysis of a pleasure yacht by user’s procedures implemented in FEMAP / NX Nastran

The objective of this study is to analyze the global structural strength of a pleasure yacht by advanced FEA approach. This is accomplished by developing and using a user FEMAP API script for equilibrating the FEA ship model, in calm water and sagging and hogging wave conditions, for different wave design heights, up to a maximum height of 6.5 meters. The FEA strength is assessed by yielding stress and buckling criteria.
