Abstract

Abstract

A drum-shaped steel wire rope isolator was applied to a two-floor steel construction to achieve a whole vibration-isolating system. Numerical simulation was carried out by the finite element method to explore the vibration-isolating efficiency of the achieved system input by explosion or shock signals with uniform forms. By changing the primary pulse duration and peak value,the vibration-isolating ratio was calculated to investigate the influences of the primary pulse duration and peak value on the vibration-isolating ratio. It is helpful to understand the vibration-isolating mechanism and develop vibration-isolating research.
- mechanics of explosion,
- shock isolation ratio,
