摘　　要：使用ANSYS有限元软件、实验模态分析技术对F320型石油井架模型的动态特性进行了数值与试验分析。从分析获得的结构动态特性信息中发现,对于这一类F320石油井架模型结构,不能用简单的线性梁模型来简化处理。本次井架模型动态特性试验结果可以作为石油井架非线性结构模型建立的数据基础。We had made numerical and modal analysis on the dynamic feature of F320 model derrick with ANSYS software and modal analysis technique.It is found that,from the structural dynamic feature information,the structures like F320 model derrick can not be simplified as simple beam in the process of numerical analysis.The results of modal analysis may be regarded as the base of data to establish the nonlinear model of F320 model derrick.
