To investigate suspension performance, we performed the test on real operating condition, and dynamic test require a lot of cost and time. In this research, we suggested a motion generation algorithm of excitation signal for a suspension dynamic test simulation system using a combined computational model of the multi-axial link type simulator and the general 4 positions supported suspension system. To verify applicavility of a suspension dynamic test simulation system and algorithm, we performed an experiment of dynamic performance test using single axial hudraulic simulator with adaptive motion generation algorithm for a real time application tool for a suspension dynamic test.
