measure of the similarity between an analytical and experimental response vector at a particular frequency
NOTE 1 The response vector assurance criterion is a vector correlation tool. It is the FRF equivalent to the MAC (see 3.2.26).
NOTE 2 The response vector assurance criterion is defined as:
- is the analytical vector containing only the FRF values at all response points due to an excitation at DOF k for a particular frequency wr
- is the corresponding experimental response vector.
NOTE 3 RVAC = 1 indicates perfect correlation of the two response vectors.
NOTE 4 FRAC = 0 indicates no correlation of the two response vectors.
