| Abstract: |
| A dynamic FE equation of the viscoelastic damper under applied stress was built based on fractional derivative Kelvin solid model，and the numerical solution was obtained by Newmark numerical integration method.The results showed that ZHANG and Shimizu’s fractional derivative numerical integration method met the requirements for accuracy，convergence and constance，and decreased the periodic error from the introduction of Newmark by reducing the time interval resulting in more accuracy of calculation. |
