Dynamic properties and modeling of wire rope isolator

In many applications numerical simulation of vibration and shock phenomenon need accurate models of flexible components connecting structural elements. Typically, simulation softwares do not include accurate models of vibration isolators. In this study dynamical behaviour of wire rope isolators are measured in different environments including underwater explosions (UNDEX), moderate vibration generated with shaker (higher frequencies) and with hydraulic test frame (static loads and lower frequencies). The purpose of the tests was to measure dynamic properties of wire rope isolator with laboratory test set-up and also in the field and to gain systematic measurement data of wire rope isolator for simulation model verification and validation. In addition, other mechanical shock isolators were studied experimentally. In this paper an overlook of the comparison of measurement and numerical simulation results is given.
