摘要
用钢球对五种木材表面进行回弹性能研究。结果表明,钢球撞击不同木材的同一断面时,e^2值随木材密度的增加而直线上升。而同一树种木材的不同切面,其径面的e^2值最大,弦面次之,横切面最小。
This paper deals with the resilince of the steel ball when it impacts on the five species of wood. The research shows that e2 value for steel ball impacting wood tends to straight increase with increase of the specific gravity of the wood when the steel ball impacts with a surface of the same type of grain of the different woods. For the different sections of the same wood species, e2 value for the radial section is the biggest, then the tengential section and the transverse section is the least.
