Abstract

A regression relationship was obtained for predicting the dimensional stability of furniture panels, in which slats made of solid beech of different cross-sections, in particular 24 mm thick, wide (B_width = 36, 60, 84 mm) and the angle of inclination of the annual layers, A_angle: tangential 0-30º; semi-radial 31-60º; radial 61-90º. The results of this study made it possible to obtain a regression equation for determining the arrow of the deflection of furniture panels Sрн, depending on the variable factors - the angle of inclination of the annual layers (х1, Aangle) and the width of the blanks (х2, B_width). Both variable factors affect in different ways: an increase in the angle reduces the deflection beam, the width is directly proportional, that is, it increases the deflection beam with an increase in width. The first factor A_angle (x1) - the angle of inclination of the annual layers in the slats - has the greatest effect on the dimensional stability of furniture boards made of hardwood species, in particular common beech with alternating stacking. It was established that the influence of the second factor Bwidth (x2) on Srn compared to the first factor Aangle (x1) is 2.4 times smaller. It was found that an increase in width from 36 to 84 mm leads to an increase in the value of the deflection arrow by 128.17-169.75% for various angles, and an increase in the angles of inclination from 0 to 90 degrees also leads to a decrease by 145.57-234.81% for different widths. According to the results of experimental studies, it was found that an increase in the width of the rails from 1:1 to 1:3.5 (thickness - width ratio) leads to an increase in the deviation from flatness (by 128.17-169.75%); increasing the angle of inclination of the annual rings to the shield layer from 0 to 90° leads to an improvement in dimensional stability (by 145.57-234.81%).
