摘要

研究在已有工作的基础上，对钢质输气管道在多种挖掘工况下的动态响应展开较全面地分析。将不同工况（驱动力油缸、挖掘高度、挖掘角度、挖掘齿数等）组合设计并实施了21组动静态试验。建立挖掘机-管道-土壤的ADAMS多体动力学模型，根据油缸压力及位移测试数据，实现STEP函数和脚本(Script)仿真控制，还原典型测试工况并获得动静态挖掘载荷，并由此判断挖掘动载系数。最后，根据模拟提取的动静态载荷，运用ANSYS/LS-DYNA得到管道测点的动静态应变，且与测试结果吻合较好。本文结合试验及模拟手段对多种挖掘工况下的斗尖动载系数进行了定量识别，研究成果对制定复杂环境下埋地输气管网挖掘破坏防控措施具有一定参考价值。

Abstract

Based on the published results recently, the dynamic responses of steel gas pipelines under various digging cases were investigated here. Total 21 static/dynamic test groups with different driving cylinders, different digging heights, different digging angles and digging teeth were designed and conducted. The excavator-pipeline-soil multi-body dynamic model was established by using ADAMS. STEP function control and Script simulation control were realized according to cylinders pressure and displacement measured data to reproduce typical test cases and to acquire dynamic/ static digging loads, then the dynamic digging load factor was determined. Finally, using the static/dynamic loading extracted from simulation, the static/dynamic strains of pipeline measured points were obtained with ANSYS/LS-DYNA, they agreed well with the measured test data. Here, the quantitative identification for dynamic digging load factors under multiple cases was conducted by using tests and simulation methods, and the results provided a reference for designing prevention and control measures against digging damages of buried steel gas pipeline network under complicated environment.
