| Abstract: | This paper presents two new methods for multiple-input experimental model analysis using random exicitation. The methods are respectively defined as the Combined Frequency Response Function (CFRF) method and the Multiple Frequency Response Function (MFRF) method. A common microcomputer is used to perform all the computation. The analytical results of a missile modal testing are given. Satisfactory results and useful conclusions have been obtained. |
