基于虚拟仪器的木材无损检测
Non-destructive Testing of Wood Composites based on Virtual Instrument
本文在图形化虚拟仪器开发环境Labview6.1下开发了应用软件，构建了木质复合材料无损检测虚拟仪器系统，结果表明:用虚拟仪器测得的动弹性模量与FFT测得的动弹性模量的相关系数为0.958，与力学实验机测得的静态弹性模量的相关系数为0.871，呈高度线性相关，可以用虚拟仪器来测定木材动弹性模量；虚拟仪器技术在木质复合材料无损检测方面具有结果准确、操作简单和成本低等优点。
In this paper，a suit of wood-based composite nondestructive virtual instrument system based on Labview was designed. The sample of poplar Laminated Veneer Lumber was used to discuss the feasibility of the applications of virtual instrument in the wood-based composite nondestructive test. The main results are as follows: the longitudinal resonance elasticity modulus that was measured by virtual instrument can be the token of conventionality static elasticity modulus and FFT because they had prominent correlation under the level of 0.01.
