摘要
针对木材特点,用控制体积有限元方法对板材模型进行网格划分,采用有限元方法将数学方程离散化,建立了木材含水率和密度空间分布的数学模型。根据数学模型建立了木材含水率和密度空间分布的三维仿真图,验证了模型的准确性。
Considering the characteristic of wood, control volume finite element method was used to design the mesh, and finite element method was used to discretisate the mathematical equation.An accurate and efficient three-dimensional computa-tional model for wood moisture content and density was built.Three-dimensional simulation results based on the computa-tional model are accurate for wood moisture content and density.
