An Improved Ground Vibration Test Method. Volume I. Research Report

摘要

Research was conducted to develop an improved method for ground vibration testing of airplanes. The resulting method, a single point excitation-frequency response analysis method, utilizes the computer, modern electronic equipment, developments in vibration testing theory and improvements in mechanical system design to accomplish ground vibration tests at greatly reduced cost while significantly improving accuracy. A demonstration ground vibration test was conducted using the improved method on an A-10 Airplane. (Author)
