| 摘 要： | 从主从系统耦合振动理论出发，基于数值实验手段，分别以船用增压锅炉、齿轮箱为研究对象，设计多种冲击输入对非一体化与一体化抗冲击分析例证进行数值计算，并将计算结果进行对比。研究结果表明，非一体化抗冲击分析方法割裂了设备与船体结构之间的耦合效应，不能精确再现船用设备实船冲击环境，中远场水下爆炸时非一体化抗冲击分析得到的设备响应结果偏大，中近场时结果偏小。建议中近场水下爆炸时肋位跨度较大的船用大型设备抗冲击性能分析采用船体与设备一体化抗冲击分析方法，若条件所限尚无法进行一体化分析，则应对非一体化抗冲击分析结果进行修正。

| Abstract: | Based on the theory for coupled vibrations of master-slave systems,numerical experiments were carried out to explore how to evaluate the shock resistance and how to design the shock protection for shipboard equipments,especially for large-scale shipboard equipments.By choosing shipboard supercharged boilers and gear cases as research objects,the non-integrated and integrated exemplification analyses were investigated numerically by devising a series of shock input data.The non-integrated analysis method for... |
