摘要：

Wire damping materials (such as Metal Rubber, MR) are used widely for protection of pipelines against vibration. A calculation method for bundle of arbitrary shape pipelines with damping supports made of MR material by finite element method ANSYS software is developed. The method takes into account complexity of pipelines shape, interaction of pipelines vibration in the bundle, multi-axial linear and torsion stiffness and damping of nipple supports. A constant damping coefficient is obtained by calculation-experimental method from vibration of one pipeline. The method allows obtaining amplitude of pipelines vibration and stress in them. Calculation results are proved by experiment. Errors of natural frequencies are less than 7 %, thus it is possible to use this method for practical application: placement of pipeline supports and design of these supports parameters. It allows reducing a large experimental work of measurement a stress in pipelines during pipeline systems design. (C) 2017 The Authors. Published by Elsevier Ltd.
