| Abstract: | In the process of random vibration controlling experiments and randomexcited modal analysing tests, the measurement of frequency response property is very important. this paper deals with a new method on measuring and calculating frequency rsponse property based on the technique of randomiza-tion noise balancing(RNB) and minicomputer controlling. Compared with the calssically repeatedly averag-ing method, the precision and efficiency of measuring Frequency Response Property with RNB are im-proved obviously. |
