Abstract
Frequency response functions are frequently used production development to identify correlation levels between designs or between analytical simulation and tests. Frequency Response Assurance Criterion is one effective method to quantify such correlations. However, practical issues such as a large number of FRFs exist and complicated modal characteristics often prevent us using the traditional FRAC analysis. A Group FRAC method was developed and is introduced in this article to resolve these application difficulties. This Group FRAC method enables automatic and efficient processing of large number of FRFs in additional to other improvements. The benefit of using the Group FRAC is evidenced through practical applications.
