摘　　要：井架是石油钻机的重要承载部件,其强度设计一直以静载荷分析为主。以瞬态动力学为理论基础,采用ANSYS软件,对井架在冲击载荷下的响应过程进行了数值模拟。分析了井架顶部和下方关键节点在响应过程中的位移规律。结果表明,井架在冲击载荷作用下,所产生的变形大大超过静载下的变形,由此将带来应力急剧增加,给井架结构安全带来隐患。The derrick is an important bearing component of the oil drilling rig. Its strength design has always been based on static load analysis. The paper is based on transient dynamics,and the ANSYS software is used for numerical simulation of the response process of the derrick under impact loading. Then,we analyzed the displacement law of the key nodes at the top and bottom of the derrick during response. The result shows that under the impact load,the deformation of the derrick greatly exceeds the deformation under static load. This will lead to a sharp increase in stress,and threat the security of the derrick structures.
