Abstract
The most commonly used methods for determination of dynamic properties are expensive and difficult to reproduce without specialised equipment. There is a need to develop simplified techniques that allow to determine specific material properties, avoiding the use of complex laboratory tests.Purpose: The aim of this work is to develop and test a simplified methodology for determining dynamic properties of various materials using pine wood as an example.Methodology: Experimental modelling using up-to-date measuring devices and analytical processing of the obtained results.Research findings: The dynamic modulus of elasticity of pine wood is determined with high accuracy and coincides with reference values. The coefficient of vibration damping is obtained for the calculation of dynamic systems in near-resonance zones.Practical implications: The proposed methodology can be used to determine the dynamic properties of new materials in order to enter these characteristics in software databases and computer complexes.Originality: The proposed method of determining the dynamic parameters of the material is based on the analysis of two-support beam vibrations registered by an accelerometer.
