Research of Stress-Strained State of Pipelines Bundle with Damping Support Made of MR Material

A calculation model for the pipelines bundle with damping support made of MR material is developed in ANSYS software. It allows for the calculation of own frequencies, vibration amplitudes and strain amplitudes for resonance. The influence of finite element type and system damping of vibration of pipelines bundle are analyzed. An experiment aiming to obtain own frequencies and strain amplitudes on resonance for pipelines bundle is fulfilled. The comparison with calculation is presented. The factors influencing the accuracy of the calculation analysis are discovered. The importance of the correct setting of constant damping coefficient is formulated, its influence on the calculation results is presented.
