| Abstract: |
Introduced the history of development of crack damage detection technology and summarized the current state of damage detection technique based on modal analysis. Finite element method is the main method for mechanical structure modal analysis at present. Many researchers studied a single crack or multiple cracks impact on different structure’s dynamic characteristics, however, these studies only limited to the current state of structures with damage. Considering damage extending when mechanical structure being on work, a new method combines modal analysis and theory of damage extend is proposed to analysis the extending trend of damage, which make it easy to assess remaining life of mechanical structures and make structures that meeting design life can still being on work before they lose their effectiveness, this can save lots of costs |
