Experimental analysis of nonlinear characteristics of absorbers with wire rope isolators

Abstract

Four different configurations of a mass supporting system consisting of a few prototypes of wire rope isolators are considered in the article. These are named "triangle,""star,""parallel,"and "serial"configurations. Reasonable models of a fixture assembly that could be utilized as models for cargo transportation are tested statically and dynamically in the laboratory. The main aim of this study is to investigate the impact of the configuration of damper settings on the effectiveness of vibration and shock isolation (in three directions) and to develop a suitable method to determine nonlinear properties and stiffness characteristics of the tested system. The purpose is also to investigate the sensitivity of the tested systems on the eccentricity of vertical loads and its influence on identification results. Experiments are carried out on the specially designed stand for the model parameters identification.
