| Abstract: | An inverse sub-structuring approach for discretized coupling unit-of-packaging in transportation packaging system is provided in this paper. Computational scheme, including relevant formula on dynamic stiffness for the unit, has been established on the basis of matrix theory. Validation on completeness and effectiveness of the formula is also provided by the lumped parameter model for a typical packaging system. The error influence of measured source function （ frequency response function） on numerical resuh has been demonstrated |
