利用黏弹性发热的复合结构脱粘的超声振动热像检测
|
Abstract:
相对于光激励的红外热像检测而言超声激励的振动热像（VT）检测是一种新兴技术，其产热机制一直为广大学者所争论。聚焦于黏弹性发热，研究了非金属材料复合结构脱粘缺陷的VT检测。以铝合金-软木复合结构脱粘的VT检测为例，通过数值模拟和实验，对缺陷的温升规律进行了分析。理论计算和实验获得了相似的结果，表明非金属材料的黏弹性发热是脱粘处产热的主导因素。这一结论为金属-非金属复合结构的脱粘及树脂基复合材料分层的VT检测提供了理论依据。 Comparing with optical thermography, vibrothermography(VT) is a new technique.However, the heat generation mechanism of VT has not yet come to an agreement among scholars. The VT of debondings in nonmetallic composite structures was studied focusing on viscoelastic heat.Taking the VT of debonding in aluminum-cork composite structures as an example, the temperature rise patterns on the defects were analyzed by using numerical simulation and experiment. The theoretical results are consistent with the experimental results, and it illustrates that the viscoelastic heat of the nonmetallic material is the leading factor of heat generation at debonding.The conclusion provides a theoretical basis for the VT of debondings in metal-nonmetal composite structures, and delaminations in polymer composite materials. 国家自然科学基金（61571028；U1433122）
