摘要
采用霍尔位置传感器测量梁弯曲位移量的方法,测量了天然木材和人造木材的杨氏弹性模量。通过对杨氏弹性模量与木材不同含水率关系的测量与分析,比较了天然椴木和人造柚木物理性能随含水率的变化情况,从而加深了实验者对弹性模量、应力、应变等物理概念的理解,加强了对测量材料力学性能的实验方法的掌握。
Young modulus of natural wood and man-made woode were measured by using the method of Hall position transducer.This article also analyzed the relationship between Young modulus of wood with different water absorbing ratio of wood and compared the change of physical performance for natural Duan wood and man-made You wood.It made us understand deeply the physics conception,such as Young modulus,stress,strain etc.,for mastering the experimentation of measuring materials mechanics performance.
