Abstract:In order to improve the antinoise ability of distributed dynamic loa d identification in frequency domain using multiresponse on a rectangular plate , an integrated method using average method, matrix pretreatment and truncated si ngular value decomposition (TSVD) were employed and modified. Guided by the idea of space mapping, this method was applied to complicated models and its applica tion area was expanded. Two simulation examples demonstrated antinoise ability of the method.
