| A parameter-type method of updating the finite element dynamics model is presented inthis paper. Because this method consists with The classical inverse eigenvalue problem,atfirst,the nonlinear equations which is equivalent to the inverse problem are conducted withrespect to design parameters,then the solvability pattern of Newton Method is described.This method,choosing the design parameters as the variables to be updated,makes updatedmodel keep original physics features and has clear engineer sense,The numerical simulatedexample has demonstrated the better charac-teristics of this method,which include the accu-racy,the convergence and the procedure. |
