摘要
为应对频发的海洋地震给石油钻井井架安全性带来的威胁,提出采用参数化塔形井架进行抗震性能分析的方法。首先利用ANSYS APDL对塔形井架进行参数化建模;其次引入时程分析法对塔形井架建立振动方程;最后将太平洋地震加速度波数据导入到ANSYS中利用APDL后处理功能,得到了海洋钻井平台塔形井架的参数化地震响应分析结果。最终证明塔形井架能够满足抗震性能的要求,为参数化海洋平台的研究提供了可行的方法。
Due to the frequent occurrence of earthquake in the sea,the seismic performance analysis of the parametric tower is proposed.The paper applies ANSYS APDL parametric to model the tower mast,takes the Pacific seismic acceleration wave data to realize the time analysis of tower mast vibration equation based on ANSYS APDL post-processing function,obtains the ocean drilling rig derrick parameterized earthquake response analysis of results.The result proves that the tower can meet the requirements of seismic performance,provide a feasible approach for the study of parametric oceanographic platforms.
