- 摘要:
- 基于动力有限元程序LS-DYNA及Euler-Lagrange耦合方法，分别以75 g柱状和200 g块状TNT炸药为爆源，对管道在爆炸载荷作用下的非线性动态响应过程进行三维数值模拟，描述了管道在不同埋深和壁厚的动力响应，并与实验结果进行了对比。研究结果为人防工程油气管道的抗爆能力分析和安全性评估提供了重要的参考依据。
By using the dynamic finite element program LS-DYNA and the coupling method Euler-Lagrange and taking 75 g columnar and 200 g blocky TNT explosive as explosion resource respectively, 3D numerical simulation is conducted on nonlinear dynamic response process of buried pipeline under the action of explosion loading, described are dynamic responses of buried pipeline in different burial depths and wall thickness conditions and comparison is conducted with experimental results. Study results provide important reference for explosion-resistant property analysis and safety assessment of oil and gas pipeline safety.
