摘要
[目的]旨在提高某型气垫船轻质船体结构在港口码头系泊或频繁靠泊过程中的碰撞性能.[方法]在ABAQUS中建立护舷和船体局部有限元模型,采用非线性有限元方法开展无护舷船体、装配橡胶护舷的船体、优化护舷支撑结构和护舷材料的船体与码头之间的碰撞动力学计算分析.[结果]结果表明,护舷支撑结构优化后使得橡胶护舷吸能比提升约 7%,复合材料护舷相比橡胶护舷在重量降低约 50%的基础上还使得吸能比提升约 13%.[结论]针对目标气垫船结构特点,提出的护舷支撑结构和复合材料护舷优化设计方案,均比优化前的橡胶护舷船体结构碰撞性能有较大提升,可为类似轻质船型的护舷设计提供参考.
Abstract
[Objective]This paper seeks to improve the collision capability of the light hull structure of a certain type of hovercraft in the process of mooring or frequent berthing at the port.[Method]A fender and local hull finite element model is established in ABAQUS,and the nonlinear finite element method is used to carry out collision dynamics analysis between the hull without a fender,the hull equipped with a rubber fender and the hull with optimized structure supporting fenders and fender materials.[Results]The optimized structure can increase the energy absorption ratio of the rubber fender by about 7%,while the composite fend-er can increase the energy absorption ratio by about 13% based on a weight reduction of about 50% compared with the rubber fender.[Conclusions]According to the structural characteristics of the target hovercraft,the optimal design scheme of structure supporting fenders and composite fender is proposed,which greatly im-proves the collision capability of the hull structure with a rubber fender compared with before optimization,thereby providing valuable references for the fender design of similar light ship types.
