木材横向切断性能螺旋管胞模拟研究.

In order to further understand wood transverse cutting performance, optimize wood processing process and reduce resource waste, based on wood tracheid theory, this paper proposed a model of wood helical tracheid structure, and carries out transverse cutting simulation study in Abaqus/ Explicit after modeling and representative volume element (RVE) uniformity. Picea abies was selected as the test material to conduct modeling based on the helical tracheid structure. Model attributes, boundary conditions, mesh division and assembly were set for simulation and post-processing. Relevant data were derived and compared with the conventional structural model simulation results and actual experimental results. The results showed that the simulation results based on helical tracheid structure were closer to the actual experimental results than the conventional structural model simulation results, which provided a favorable reference for future wood simulation research and wood processing optimization.
