The objective of this study was to examine the potential of stress wave velocity (SWV) as a rapid and non-destructive method to estimate the mechanical properties of Melia azedarach wood. The SWV, dynamic modulus of elasticity (MOE_d), modulus of elasticity (MOE), modulus of rupture (MOR, bending strength) and density were determined on ninety 20 ⋅ 20 ⋅ 320 mm clear wood specimens, obtained from stems of three ten-year-old M. azedarach trees, and tested at environmental equilibrium in 20°C, 60 % relative humidity (a moisture content of approximately 12 %). There was a statistically significant (0.1 % level) but weak correlation (R² = 0.23) between the SWV and MOE, but no statistically significant correlation was found between the SWV and MOR. Much better results for prediction of static properties of M. azedarach wood were obtained when SWV and wood density (WD) were used together through calculation of MOE_d in the air-dry condition (MOE: R² = 0.76, MOR: R² = 0.47), although in the case of MOR a model based on WD alone is slightly better (R² = 0.58), and WD is also almost as good as MOE_d for predicting MOE. It is concluded that SWV coupled with WD can be employed as a predicting parameter to evaluate the mechanical properties of M. azedarach wood during the manufacturing process, although WD alone is also effective. The SWV alone would not be useful due to MOE being almost directly proportional to WD at this moisture content.

这项研究的目的是检查应力波速度（SWV）的潜力，作为一种快速而无损的方法来估算Mel木（Melia azedarach）木材的机械性能。在90个20⋅20⋅320 mm的透明木材样品上确定了SWV，动态弹性模量（MOE _d），弹性模量（MOE），断裂模量（MOR，弯曲强度）和密度，这些样品是从三个十个茎上获得的岁的M. azedarach树，并在20°C，60％相对湿度（湿度约12％）的环境平衡下进行测试。有统计学上的显着意义（0.1％的水平），但相关性较弱（R ² SWV和MOE之间的关系= 0.23），但SWV和MOR之间没有统计学上的显着相关性。通过在风干条件下计算MOE _d，将SWV和木材密度（WD）一起使用时，可以更好地预测a蓝木的静态特性（MOE：R ²  = 0.76，MOR：R ²  = 0.47），尽管在MOR的情况下，仅基于WD的模型会更好（R ²  = 0.58），并且WD在预测MOE方面也几乎与MOE _d一样好。结论是SWV结合WD可以作为预测参数来评估M. azedarach的力学性能木材在制造过程中，尽管单独使用WD也有效。由于在这种水分含量下MOE几乎与WD成正比，因此单独使用SWV并不会有用。
