摘　　要：文章基于ANSYS软件和ADAMS软件运用动态子结构法对井塔结构与提升机系统进行耦合振动分析,得出井塔结构与提升机系统的动力学响应,并与实际测量结果进行了对比,以检验动态子结构法在井塔结构与提升机系统耦合振动分析中的效果。首先,在ANSYS中建立井塔结构有限元模型,通过多步静力学分析得到井塔结构与提升系统耦合界面的等效刚度矩阵K;然后,建立提升机系统ADAMS模型,将井塔结构等效矩阵K以力的函数表达式作用于提升机系统上,计算得到提升机振动响应和提升机系统对井塔结构的作用力;最后,将ADAMS计算得到的作用力作用于井塔结构上,计算出井塔结构的动力学响应。计算结果表明文中方法的效果是比较理想的。Based on ANSYS and ADAMS ,the dynamic substructure method is used to analyze the cou-pling vibration of the well tower structure and hoisting system .The dynamic responses of the well tower structure and hoisting system are obtained and compared with the actual measured values to ver-ify the efficiency of the dynamic substructure method in coupling vibration analysis .Firstly ,the finite element model of the well tower structure is established in ANSYS and the equivalent stiffness matrix K of the well tower structure in the coupled interface is obtained by multi-step static analysis .Then the ADAMS model of the hoisting system is established and the forces expressed by the equivalent matrix K are applied to the hoisting system .Therefore ,the vibration response of the hoisting system and the force F applied to the well tower structure are calculated .Finally ,the force F calculated by ADAMS is acted to the well tower structure and the dynamic responses of the well tower structure are calculated .T he results show the effectiveness of the presented method .
