In this paper, the mapping technique of the structure dynamic response measured in
tests is researched. The time domain dynamic response of arbitrary freedom in a structure can be
mapped from the structure-dynamic response data which are obtained from the dynamical test on
the condition of force and displacement excitement through the Fourier transformation and matrix
calculation based on precise structure-dynamic finite element model. The expressions of the
response mapping are deduced too. Some fields in which the response mapping method is feasible
and the problems existed are also introduced in the paper. The feasibility of the technique is
proved by an example of a structure response test with basement exciting. The mapping method
has been programmed and integrated with MSC/NASTRAN software.
