Abstract
The aim of this paper is to present some aspects of 3D modeling of wire rope isolators which will be used for modal analysis with finite element method. The behavior of wire rope under axial loads have been addressed by some recent researchers, but little information is available to design a complete wire rope isolator and to simulate the laying process of wire rope taking in account the frictional phenomenon between wires. First important step, starting to use the wire parametric equation of single and double helical and following de geometry of wire rope isolator, was to create a 3D model. The model was made using an independent wire rope core (IWRC) which is one of the fundamental and complex components of wire rope isolator. Second step, using the finite element method, was to define the frictional phenomenon between wires of the rope and to check the impact of the friction in modal behavior for wire rope isolator.
