| 摘 要： | 舰艇管路系统的抗冲击安全性能是其生命力要素的重要组成部分,因此对舰艇管路的抗冲击设计分析方法的需求也十分迫切.本文以火力发电厂汽水管路设计计算方法为原理,对容易破坏的管路部件的应力增强系数进行验证性计算,提出了多点支撑管路系统的冲击载荷输入方法,给出了管路系统的抗冲击性能评估方法.通过试验,验证了评估方法具有足够的安全系数,可以作为舰艇管路系统抗冲击性能的评估方法.

| Abstract: | The anti-shock strength of shipboard pipelines is one of the important elements of ship survivability,so there is an exigent demand for the calculation of the anti-shock strength of shipboard pipelines.Based on the theory applied to the calculation of steam pipelines,the stress strengthening facts of weakness parts of pipelines are calculated for verification.A method for applying shock loading and safety evaluation of shipboard pipelines is presented.This method is proven to be of enough safety factors by a special designed shock test. It can be applied to engineering. |
