本文选择了8种主要云杉属树种,进行了弯曲振动条件下各项声振动特性参数的检测和比较,并分析了这些参数和木材构造中生长轮宽度、晚材率之间的关系,为深入评价云杉属乐器材品质,确立乐器材选材中合理应用木材生长轮宽度、晚材率参数的方法打下了基础
In this paper eight Picea genera wood were selected to determine and compare the sound vibration parameters of Young‘s module,loss tangent (tan δ) and E/G under bending vibration condition.The relationship between these parameters and growth ring width and latewood percentage was analyzed.The results of this study could be a basis of evaluating the quality of Pices genera wood for musical instrument and establishing the method of reasonably using the parameters of growth ring width and latewood percentage in the selection of wood for musical instrument production.
