This paper describes the application of experimental statistical energy analysis (SEA) in order to estimate the mid and high frequency vibration response on space utility vehicle (SUV). The power plant and the trim are removed from the SUV. The number of subsystems on SUV is 38. The basic impact- hammering test is carried out to construct the SEA model. The approximated power injection method is employed to evaluate internal and coupling loss factors. The constructed SEA model is verified by shaker test on one engine mount. Furthermore, the subsystem division methodology for chassis frame and the prediction of structural modification effect are discussed.
