摘要
根据结构稳定理论,使用ANSYS软件对JJ225/43-K型石油钻机井架进行了屈曲分析,得到了该井架在线性屈曲、几何非线性屈曲和双重非线性屈曲3种情形下的临界失稳载荷。通过对比分析可全面了解该井架的稳定性能,为安全使用提供依据。
A buckling analysis was made of JJ225/43-K type oil rig derricks using ANSYS software based on the stable theory of structure,the critical unstability load was obtained under the linear buckling,geometrical non-linear buckling,and double non-linear buckling conditions of the derricks.The stability of the derricks was totally recognized through comparisons and analyses,and some bases were provided for references.
