A 1/5 scale replica model of the H-II launch vehicle was constructed and tested for study of vehicle dynamics. This model was designed to duplicate, in miniature, as many of the full scale structural elements as was economically and technically feasible. A series of vibration tests, from the moving launcher phase to the second-stage burn-out phase, were carried out, and resonant frequencies, mode shapes, and modal dampings were measured for each case. The test data verified the mathematical modeling techniques used for predicting the vibration characteristics of the various configurations of the H-II launch vehicle.
