Abstract: A new technique to measure structural inertia parameters is presented in this paper. The structure to be measured is flexible supported,Using dynamic test equipment,the structure is excited,responses and forces are measured.Through signal analysis and parameter estimation,all inertia parameters of the structure can be obtained.Simulation and application of a beam dem-onstrate that the technique presented here is feasible effective,and very useful in many fields.

Key words: inertia property, estimation, dynamic test
