| Abstract: | This paper established a Galerkin method for transforming constrained-structure test modes to free-structure test modes (GMTCF). In addition, the ways for further developing GMTCF are pointed out in the paper. Numerical examples show that the GMTCF is feasible and can be directly applied to some real engineering-problems. |
