| 8. | Its principle is : a laminated structure ( beam or plate ) with delamination consists of undelaminated region and delaminted region which can be divided to upper and lower parts . when a low - amplitude and high - frequency excitation has the frequency close to some part ' s natural frequency , this part will resonate and certain amount of mechanical energy will convert to heat so that the delaminated region ' s temperature exceeds greatly that of the undelaminated region . therefore the delamination can be located by means of infrared thermograph
其原理是具有脱层的层合材料构件(梁或板)包含脱层区域及未脱层区域，脱层区域分为上下两部分，若对层合材料构件施加小振幅、高频率的振动激励，当激励频率恰好接近其中一部分的固有频率时，该部分就会产生共振响应，部分机械能将转化为热能，使脱层区域的温度远高于未脱层区域，借助红外热像仪即可显示出脱层的位置。 |
