摘要:
针对复合材料气瓶分层缺陷不易被检测的问题,利用ANSYS有限元方法、红外检测技术,对复合材料气瓶分层缺陷进行红外模拟分析. 研究了复合材料气瓶分层缺陷不同直径、深度、厚度对复合材料气瓶表面热像温度差、热像对比度的影响. 结果表明,随着缺陷直径和缺陷厚度的增大,热像温度差峰值和热像对比度峰值也随着增大,说明分层缺陷越容易被检测出;随着缺陷深度的增大,热像温度差峰值和热像对比度峰值与深度呈反比关系,说明分层缺陷深度越小时,缺陷越容易被检测出.
Abstract:
Aiming at the problem that the delamination defect of a composite cylinder can not be detected easily,we carried out infrared simulation analysis of the composite cylinder delamination defect through the ANSYS finite element method and the infrared detection technology. The paper studies the effects of different diameters, depths and thicknesses of composite cylinder delamination defect on temperature difference and contrast ratio of thermal imaging on the surface of composite cylinder. The results show that the peaks of temperature difference and contrast ratio of thermal imaging increase with the increase of defect diameter and thickness, which means that the delamination defect can be more easily detected. The peak of temperature difference and contrast ratio of thermal imaging are inversely proportional to defect depth, which proves that the delamination defect is more easily detected at the smaller defect depth.
