| Abstract: | A prediction of vibrational power flow of structure borne sound which involves vertical translational component and two horizontal rotational components is conducted by using the knowledge of the free source velocities of the machine,the admittance of the floors and the stiffness of the anti vibration mounts.The comparisons are made between the different components and the floors with different size. |
| |
| Keywords: | free source velocity point mobility of floor vibrational power flow |
