Two conditions, as no table working and 2 tables working with sines input of different frequencies from 1 to 40 Hz and peak acceleration of 0.5 g are included. By vibration attenuation curve from the test result, the damping ratio of different frequency is got and the effectiveness of the large mass stiffness is also verified for vibration reduction.
