| Abstract: | An simplified and new equation,which describing the relationship of temperature and time (frequency) equivalence of polymer materials' property,is given.Based on dynamic mechanics properties of the prepared polyurethane elastomers,the validity of the equation was proved.At the basis of the equation,we predict the damping performance of polyurethane at frequencies of 7.5 Hz,44.9 Hz and 57.4 Hz.Then the free damping layer treatment structure was prepared.And its structural damping factor under steady-state vibration at corresponding frequencies were tested.The results showed that predicted and experimental results had the same changing trend. |
