| Abstract: | The discrete
element method (DEM) model of two-level isolation system impacted by external force is
developed. The relations between the dynamics characteristics of two-level isolation
system and the duration times and wave-type of impact are studied together with the
non-linear effects on the dynamics characteristics of the system by computer simulation. A
new approach is provided for parameter design of two-level isolation system impacted by
external force, consequently. |
