【摘要】 文摘蜂窝胶接结构使用敲击法检测时,由于蒙皮厚度增加导致检测灵敏度降低。本文针对这一不足,设计了一套由控制计算机、扫查机构、敲击锤等组成的敲击检测系统,旨在通过自动机械控制技术与C扫描显示技术相结合,直观显示全面的产品检测数据,使检测灵敏度、检测可靠性得到提高。为验证系统检测效果,在胶接结构试样中设计了人工缺陷,针对试样检测结果表明,系统检测效果良好,适用于实际产品检测,有利于实现对产品质量检测结果的客观评价。更多还原

【Abstract】 When coin-tap method is applied to test honeycomb bonding structure,the detection sensitivity is reduced due to the increase of the skin thickness. To overcome this shortcoming,this paper designs a set of detection system consisting of computer,scanning mechanism and percussion hammer. The work improves the detection sensitivity and reliability of the product by combining the automatic control technology and C-scanning display technology. To verify system testing effects,artificial defects were designed. Experimental results are then presented which show good quantitative agreement with the artificial defects. As a result,the system is suitable for the product testing and beneficial to the objective evaluation of product quality.更多还原
