Abstract

Steel is used in construction, Bridges, ships, boilers and other projects on the metal structure, or is used in the manufacture of machinery and equipment parts, which can produce defects such as corrosion and crack due to the effect of load and environment. In order to ensure the healthy use of steel, it is necessary to carry out defect detection. Therefore, a method to detect steel defects based on modal analysis is proposed in this paper. Theoretical model of square steel, which both ends are fixed, was studied. By theoretical simulation, the influence of defects shape and size on modal parameters was studied. The results showed that some order modes change significantly in the modal analysis with the increase of the radius of corrosion defects, and some order modes change significantly in the modal analysis with the increase of the width of crack defect. So, the size of defects can be characterized by the frequency variation of some orders.
