摘要：

There is renewed interest in normal mode testing sparked by advances in shaker control automation and modern aircraft fabrication methods. This article covers the use of appropriated excitation of a structure to assure that only one mode shape is excited. Modes are separated physically rather than mathematically. The technique is applied to ground vibration tests of a new aircraft.
