| 摘 要： | 针对Lamb渡检测胶接结构脱粘缺陷时如何选择恰当的模式这一问题,研究了板内质点振动位移与检测灵敏度之间的关系.以钢板/橡胶胶接结构为例,用不同模式的Lamb波进行了检测试验研究.结果表明,不同模式的波有不同的检测灵敏度,选择在板表面具有较大位移而在板内具有较小位移的Lamb波模式,可以提高胶接结构脱粘缺陷检测灵敏度.

| Abstract: | According to the problem of mode selection for detecting disbonding in adhesive bonding structure by using Lamb waves, the relationship between vibration displacement of points in plate and sensitivity of disbonding testing is studied. The experiments are carried out on the steel/rubber adhesive bonding structure by using Lamb waves of different modes. The results show that testing sensitivity of different Lamb waves are different, and a high sensitivity of disbonding testing can be reached by selecting the... |
