本文是根据短时间的木材弯曲蠕变实验曲线来确定粘弹性模型元件数和元件常数的探讨.通过核桃楸试件三点弯曲蠕变的实验研究表明:实测蠕变曲线与模型的计算曲线有较高的拟合度.因此我们认为在木材物性研究上或在工程应用上可以采用粘弹性模型元件常数.而且在各树种和环境条件下,一旦确定了适合其蠕变的元件数和元件常数,就将和力学性质中的常数一样,来表示蠕变度量,这将给木材的蠕变研究和木材的应用带来很大方便.
This article is based on a short time curve of wood bending creep test to determine the number of viscoelastic components and component constant.Through the Juglans mandshurica three point creep experimental study shows that: the measured creep curve and the model of the calculation curve with Therefore, we believe that viscoelastic model element constants can be used in the study of wood properties or in engineering applications.On the condition of tree species and environmental conditions, once the number of components and component constants , Will be the same as the constants in the mechanical properties to indicate the creep measure, which will bring great convenience to the study of the creep of wood and the application of wood.
