摘要：

Wire rope isolator (WRI) is widely used in the power machinery and chemical equipment, and has a better dry friction damping and stiffness softening characteristics compared with other vibration isolators. The aim of this article is to create a simplified finite element model of polycal WRI and to avoid the use of overall model on the stiffness characteristic caused by the waste of time. The numerical simulation method used in this paper is to simplify the 1 + 6 +12 single strand into a single wire. The simplified WRI model subjects to the compression load by finite element analysis and obtained the vertical static stiffness characteristics which are consistent with the experimental results.
