摘　　要：以实模态分析理论为基础,对钻架模型系统进行典型试验模态分析和基于ODS(Operation Deflection Shapes)测试方法为基础的试验模态分析,分别识别出系统的模态参数,并进行对比分析。Based on real modal analysis theories, take model of drill pipe frame as an example, classical experimental modal analysis and experimental modal analysis based on ODS＇s testing method is studied, the modal parameter is distinguished and the testing result are analyzed and are simultaneously compared to modal parameters identified by classical modal testing methodS.

关 键 词：试验模态分析 模态参数识别 ODS测试方法 钻架模型
