摘要

本文介绍了枫木在弦乐器结构中的粘弹性行为的实验研究。所研究的样品根据木材的解剖结构分为乐器制造商使用的四类解剖质量。基于动态状态下的力学分析，分别确定了在恒温和变温条件下的粘弹性参数——保持模量E’、损耗模量E’和阻尼tanδ。研究发现，确定的流变量取决于木材的解剖结构、激发频率和温度。

EVALUATION OF VISCOUS-ELASTIC PROPERTIES OF RESONANCE MAPLE WOOD

The paper presents the experimental investigations regarding the viscoelastic behaviour of maple wood used in the construction of stringed musical instruments. The studied samples were classified according to the anatomical structure of the wood in the four classes of anatomical quality used by the manufacturers of musical instruments. Based on the mechanical analysis in dynamic regime, the viscoelastic parameters were determined - the preservation module E', the loss modulus E' and the damping tan δ, in conditions of constant temperature, respectively variable temperature. It was found that the determined rheological quantities depend on the anatomical structure of the wood, the frequency of the excitation and the temperature.
