Abstract

The article provides a brief overview of methods for determining the wood density, which according to the classification are divided into direct and indirect. A mathematically justified author's method for determining the wood density, taking into account the laws of physics, is proposed, which is a kind of water displacement method. Experimental studies have been conducted on nine types of wood, which have shown the efficiency and applicability of the method. The data obtained by the stereometric method were compared (the error value was less than 3 %). The conditions for selecting a load in the form of a ball for research are determined in such a way that incomplete immersion of the sample occurs while ensuring vertical position in a liquid medium. It is recommended to use the proposed method to determine the density of wood in the field conditions.
