摘要
基于红外热成像技术,利用橡胶加热带对设有缺陷的钢管混凝土柱进行加热,在缺陷区域钢管壁形成温度差,探索利用橡胶加热带检测钢管混凝土密实性。利用ANSYS有限元分析软件,对加热时间、加热温度、缺陷尺寸大小进行模拟分析,结果表明,利用加热带加热的方法可以清晰的辨别出100 mm×100 mm×10 mm(5 mm)的大缺陷,以及50 mm×50 mm×10 mm(5 mm)的小缺陷。
Based on the thermal imaging technology, the rubber heater band is used to heat the steel pipe concrete column with defects, and then the temperature difference is formed at defect oreas. The detecting on compactness of concrete filled steel tube is studied. The ANSYS is used to simulate the heating time, heating temperature, defect size. The results show that the use of heating belt can clearly distinguish 100 mm×100 mm×10 mm（5 ram） of the defect, and 50 mm× 50 mm×10 mm（5 mm） of small defects.
