NUMERICAL AND EXPERIMENTAL ANALYSIS OF DYNAMIC PROPERTIES OF A COMPOSITE HYDRAULIC MICROHOSE

Abstract

: The paper presents an analysis of driven vibrations of a hydraulic microhose made of a composite material. The test object was a hydraulic flexible hose with an internal diameter of 2 mm and a length of 960 mm. The vibrations of the object were driven by the electrodynamic actuator, and they were recorded with a laser vibrometer. At the same time, numerical analysis of such an object was carried out using the finite element method. The results of numerical and experimental studies were compared and the possible causes of discrepancies were pointed out. Such calculations should be accompanied by experimental verification. This work is an attempt of numerical and experimental analysis of vibrations of a microhydraulic hose and determination of the usefulness of a selected numerical method.
