根据船舶管路系统及元器件布置的特点，利用具有分布集中质量的等效连续梁模型，建立典型管路的力学简化模型。在此基础上结合参数化建模技术、有限元分析技术，分别以固定约束、简支约束和弹簧约束作为模拟约束条件，进行数值计算。回归出典型管路位移响应幅值、应力响应幅值简化计算公式中的各参数，进而获得管路系统抗冲击性能的工程简化计算公式。%Based on the characteristics of the ship pipeline systems and components' layout, establish the simplified mechanics model of typical pipeline taking the advantage of equivalent continuous beam model with concentrated mass distribution. On this basis, numerical calculation was conducted using parametric modeling techniques and finite element analysis technology under the simulation constraint conditions such as fixed constraint, simply supported constraint and spring constraint. Regressed the parameters in the calculation formulas of displacement response amplitude and stress response amplitude, and then obtained engineering simplified calculation formulas of impact resistance for typical pipeline systems.
