为解决船舶设备抗冲击评估软件对外依赖度较高的问题，本文设计并实现了一款基于动态设计分析方法（Dynamic Design Analysis Method，DDAM）的船舶设备抗冲击评估系统。该系统依托于海洋结构分析软件（Structure Analysis of Marine Structures，SAM）进行深度开发，在继承SAM软件通用功能模块的基础上，进一步研发抗冲击评估系统专用的前后处理模块和核心计算模块，其中前后处理模块按照DDAM的计算流程设置并管理响应谱曲线、响应谱分析任务，核心计算模块采用本文提出的一种基于DDAM的设备抗冲击密集模态分析方法，在响应谱分析的基础上处理密集模态的影响。典型算例船舶柜体设备测试结果表明，本文研发的系统能够精确高效地完成模型的导入显示、前后处理以及求解计算，计算结果与商用软件偏差小于0.1%，实现了船舶设备抗冲击评估的自主可控。
To address the high external dependency of ship equipment shock resistance evaluation software, this paper presents the design and implementation of a ship equipment shock resistance evaluation system based on the Dynamic Design Analysis Method (DDAM). This system undergoes in-depth development with reliance on the marine structure analysis software SAM. While inheriting the general functional modules of SAM, it further develops specialized preprocessing and postprocessing modules as well as a core computational module for the shock resistance evaluation system. Specifically, the preprocessing and postprocessing modules are configured to set and manage response spectrum curves and analysis tasks according to the DDAM computation process. The core computational module employs a dense modal analysis method for equipment shock resistance based on DDAM, which processes the effects of dense modes on the basis of response spectrum analysis. Test results from a typical example of ship cabinet equipment demonstrate that the system developed in this paper can accurately and efficiently perform model import, display, preprocessing and postprocessing, as well as solution computation. The computation results deviate less than 0.1% from commercial software results.
