随着在工业制品中木料得到越来越广泛的应用，对木料性能的研究变得尤为重要。本文研究了大量使用的木棒刚度分类的工业方法，并采用微机控制气动机构实时检测木棒的弹性模量，用气缸进行自动快速分类存放。以此建立的系统通过工厂应用，代替了人工木棒分类，大大提高效率和精度。 As wood is more and more widely used in industrial products, the study of wood properties becomes even more important. In this paper, an industrial method for massively classifying wood rods has been studied, and the elastic modulus of the wood rods has been measured in real time by a microcomputer-controlled pneumatic mechanism. The cylinder is automatically and quickly sorted and stored. The system thus established was replaced by a manual stick classification through factory applications, greatly improving efficiency and accuracy.
