| Abstract: | Based upon complex modal synthesis and optimization techniques, a method for identifying physical parameters of substructures is proposed in this paper. In this method, the physical parameter identification equation in the system of general coordinates is constructed at first and then, the unknown substructural parameters are solved by use of optimization method. A practical example of the identification of the local physical parameters of a drilling mechine is given to show the effectiveness of this method. |
