摘要
选择7种我国主要的云杉属树种木材和1种作对比用的美国产西加云杉,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,初步分析了这些振动参数与木材构造中生长轮宽度变异系数之间的关系。结果表明:生长轮宽度比较均匀的木材具有比较好的声学振动特性。
Eight species of Picea wood were selected as experimental materials, among which one species produced in America was used as control. The Young＇s module, loss tangent （tang） , E/G parameters were examined and compared under bending vibration situation. Relationship between test data and variance coefficient of growth ring width was analyzed. Result showed that wood with even growth ring width had good vibration character, which would help to explain the effect of wood variance coefficient of growth ring on the vibration property of wood used to make musical instruments.
