| 摘 要： | 本文介绍了小水线面双体船后鳍机构的组成及主要设计输入,采用经典算法计算了鳍轴在正常工作时的应力,采用有限元分析法计算了鳍柄的应力,并将此应力与航行试验时通过应变片实测的应力进行对比。对比结果表明,两者误差百分比约为4%,在工程许可的误差范围内。

| Abstract: | The components of the after fin of SWATH is introduced in this paper, then the stress of the fin shaft is calculated classically, the stress of the fin crane is simulated via FEM afterwards, then a comparison of the stress calculated with the sea test is accomplished with a result of difference less than 4%, which is acceptable in engineering. |

| Keywords: | after fin of SWATH, strength analysis, stress comparison |
