摘　　要：针对大型水面舰船的波浪设计载荷计算,首先研究了国内外三种军规中的波浪载荷设计值计算方法,以某大型水面舰船为例,得到其设计载荷,并在拖曳水池中对该船进行了分段模型载荷试验.通过规范计算结果和试验结果的比较发现:现行军规对砰击弯矩的考虑不够充分,相对于模型试验结果规范得到的砰击弯矩值偏小而波浪弯矩值偏大.所得到的大型水面舰船波浪设计载荷特性可以为该型船舶波浪载荷理论计算的验证和改进提供参考,也为船体结构设计和有限元直接计算提供了依据.Design wave calculation methods of large surface warship was focused on .The methods of design wave loads from the native existing classification society′s rules and foreign rules were studied , and based on these rules the design loads of a warship were obtained .Meanwhile ,segment model tests of this ship were performed in the seakeeping tank to confirm the design values .Comparisons of calculation of classification society′s rules with experimental data were also conducted and results were summarized .It is concluded that the evaluation methods from the rules don′t take full account of the importance of slamming ,and the slamming moments from rules are fewer and wave moments are too large .The wave loads characteristics of large surface warship can be understand ,which can not only give references for validation and improvement of the theory calculation ,but also give help for hull structure design and FEM estimation .
