摘要
采用"悬臂梁"自由端的方式,测定了三层胶合板材的动态弹性模量E动、阻尼比ξ以及试件的静态弹性模量E静。结果表明,其动、静态弹性模量测量值相差很小,但动态测试快速、简便、重复性好。
The thesis adopted the mode of ＂cantalever grider＂ freeness end, measured dynamic elasticity modulus and damp ratio of three layers plywood test materials. The result shew that its dynamic elasticity modulus and static elasticity modulus complexions were basically consistent, but the dynamic testing was of merits of speediness, easy and repetition, etc.
