摘要
应用振动无损检测法测定纤维板的动弹性模量,并与力学试验机测定的静弹性模量进行比较。结果表明,应用振动法测得的纤维板弹性模量精度高,动弹性模量与静弹性模量呈密切线性相关。建立了纤维板的动态特性无损检测系统。
Vibration-based non-destructive detection method is adopted to measure the dynamic elastic modulus of fiberboard which is compared with the static elastic modulus measured by a mechanical test machine. The results indicate that the dynamic elastic modules of fiberboard measured by the vibration method is of higher accuracy and that the correlation between the static elastic modules and dynamic elastic modulus is linear. A non-destructive detection system for detecting dynamic properties of fiberboard is established.
