| description | If an unexpected vibration or force is expected to be generated during operation, a vibration mount must be installed beneath the support system. A mass-block can be considered to reduce the structure basement fundamental frequency of the basement. Thus, the efficiency of a single-mount or mass-block can be enhanced by implementing a single-mount module called a mass-block integrated mount module (MIMM). This study addressed the tuning process of multiple mount modules in a supported system by evaluating the mount module using the proposed total performance index, building on a previous evaluation method comprising the first and second performance indices. This index was subsequently applied to assess the control capability of MIMM concerning both the self-excitation of an electric power plant and basement input. The extended 3-degrees-of-freedom (3-d.o.f.) electric power generator model was applied to determine the best selection of the mechanical properties for the MIMM over the various mechanical parameter settings (ranging between 10 and 1000% of the original parameters) of the two sub-mounts. The simulation results demonstrate a reduction in the total performance index from 8.2, as calculated in a previous study, to 0.2. The novelty of the optimal MIMM conditions is confirmed by the simultaneous enhancement of both performance indices. |
