review text: A technique is developed which reduces the order of analytical finite element model, and enables design sensitivity analysis to be performed efficiently by suitable selection of master and slave coordinates. Also, a method for calculating eigenvalue and eigenvector derivatives via the reduced-order analytical model is presented and applied to structural design practice to predict the changes of eigenvalues and eigenvectors for given structural modifications as well as to tailor the eigenvalues and eigenvectors by identifying the structural modifications required. A realistic structural model is used to demonstrate the concept developed, and results are compared with those from the analysis of original full analytical model. Possible integration of the proposed techniques into commercial finite element analysis software is discussed.
