本文阐述高速铝制双体船的强度评估方法。以1艘高速铝制海监船为例，探究总纵弯矩的分布曲线、总扭矩施加位置等因素对船舶结构强度的影响。在此基础上对全船结构强度作出评估，提出若干合理建议。相关结论对同类型船舶的结构设计提供了一定的参考。
In this paper, the evaluation method of the structure strength for the aluminum high-speed catamaran is discussed in detail. The influences to the strength for the aluminum high-speed catamaran of marine monitoring are analyzed and compared based on these two aspects:the calculation methods about the longitudinal bending moment distribution curve and applied positon of the total torque. Furthermore evaluations are achieved in the way of dangerous loading, and some recommendations are put forward. The related results have certain reference significance for structure design of similar vessels.
