This paper presents a frequency-domain experimental setup for modal analysis of mechatronic and suspension system components. Design, instrumentation and dynamic behavior of the one degree-of-freedom (DOF) system, capable of providing both, periodic and application-specific, excitation forces is described. The excitation is realized by an electromagnetic modal shaker with additional assembly and interface components designed and instrumented for frequency -domain analysis of vertical dynamics. Frequency response functions (FRFs) of the implemented system are experimentally measured and the associated basic model parameters are calculated, correspondingly identified. Accurate fit between the measured FRFs and modeled dynamics is shown for sufficiently large frequency range 0.1-30 Hz of the mechanical system response. Exemplary standard road profile excitations are also conducted to demonstrate the applicability of the designed system for frequency-domain testing of components in the vehicle suspension systems.
