- Abstract:
- Rigid blocking masses are located in the typical base structure of a power cabin based on the impedance mismatch principle. By combining the acoustic-structural coupling method and statistical energy analysis, the full-band vibration and sound radiation reduction effect of vibration isolation masses located in a base structure was researched. The influence of the blocking mass’ cross-section size and shape parameters and the layout location of the base isolation performance was discussed. Furthermore, the effectiveness of rigid vibration isolation design of the base structure was validated. The results show that the medium and high frequency vibration and sound radiation of a power cabin are effectively reduced by a blocking mass. Concerning weight increment and section requirement, suitably increasing the blocking mass size and section height and reducing section width can result in an efficiency-cost ratio.
