| Abstract [eng] |
The paper presents dynamic studies of oak scantlings and glued-up panels. The scheme of sawing of scantlings in a log is presented and their coefficient of damping is determined. Distribution regularities of the coefficient of damping in a log, estimated along and across the grain, are provided. It was found, that the highest coefficient of damping along the grain is in the buttlog (0.0265 – 0.0266), while the lowest – in the top end (about 0.0263). The regularity of coefficient of damping variation across the grain is different – the highest is at the ends of a log (0.0306 – 0.0330), while in the centre – the lowest (0.0304 – 0.0315). The influence of coefficient of damping of scantlings on panel coefficient of damping was estimated. It is shown, that panel coefficient of damping is in all cases lower than mean coefficient of damping of comprising it scantlings. Statistical processing of the obtained results is presented. |
