Abstract

This paper presents a study of the deformations of the birch veneer layer of plywood composed of veneer sheets, each with a thickness of 1.4 mm. Displacements in the longitudinal and transverse directions were analyzed in each layer of veneer from the composition of the board. Cutting pressure was applied to the surface equal to the diameter of the water jet, located in the center of the laminated wood board. Finite element analysis (FEA) does not study the breaking of the material or its elastic deformation, but only what happens from a static point of view when maximum pressure acts on the board, which causes detachment of the veneer particles. The results of the finite element analysis indicate maximum values of 0.0012 mm in the longitudinal direction of the board located in the proximity of the application of the maximum force of the water jet. Additionally, in order to analyze the recorded differences between both longitudinal and transversal displacements, estimation of statistical parameters with 95% confidence intervals (CI) was applied. The comparative results indicate that the differences are not significant for the displacements under study.

摘要

本文介绍了一项对由单板片组成的胶合板桦木单板层变形的研究，每个单板片的厚度为1.4毫米。从板材的组成来看，对每层单板的纵向和横向位移进行了分析。将等于水射流直径的切割压力施加到位于层压木板中心的表面上。有限元分析（FEA）不研究材料的断裂或其弹性变形，而仅研究当最大压力作用于板材时从静态角度发生的情况，这会导致单板颗粒分离。有限元分析结果表明，在靠近水射流最大力施加位置的板材纵向方向上，最大值为0.0012毫米。此外，为了分析记录的纵向和横向位移之间的差异，应用了具有95%置信区间（CI）的统计参数估计。比较结果表明，所研究的位移差异不显著。
