摘要
舰船管路是船舶抗冲击的薄弱环节之一,开展船舶管路抗冲击研究对提高舰船生命力很有意义。文中对大型船舶的压缩排气管路进行有限元建模,并基于有限元计算,分析了管路模型在水下爆炸冲击载荷作用下的响应。通过对管路应力、应变、加速度和位移等响应的归纳,得到空气管路在水下爆炸载荷作用下的响应规律并给出结论,可以为船舶管路系统的抗冲击研究提供参考。
Pipeline is one of the weaknesses in anti-impacting capaty of stops,winchsignificant for improving the life of warships. This paper models the compressor exhaust pipelines by FEM. It analyzes the response of the model to the impact loads due to the underwater explosion. The response characteristicsof the air pipelines subjected to the underwater explosion is concluded from the analyses of piping stress, strain, acceleration and displacement. It can provide references for the investigation of anti-impacting capability of warship piping systems.
