    The resonance behavior of supporting mount modules can significantly degrade vibration isolation performance in mechanical systems. To address this issue, the dynamic influence of mount modules must be thoroughly investigated. A simplified theoretical model of a rigid body-supported system, comprising upper and lower mounts with an intermediary mass, was developed using linear system modeling. Frequency response functions were used to characterize the dynamics of the mounts, and experimental modal tests were conducted on a setup with and without intermediary mass. The inclusion of the mass shifted the translational rigid mode from 38.1 Hz to 29.5 Hz and introduced a rotational mode at 66.9 Hz. Both of these effects were influenced by the mount module’s resonance at 55.5 Hz. These results highlight the critical impact of mount module resonance on supported system dynamics, underscoring the need to integrate mount dynamics into system-level analyses for accurate vibration behavior predictions.
