Beam Damage Detection And Wavelet Response Under Moving Loads

With the development of modern economic, an increasing number of bridges are appliedto the traffic and facilitating people’s life effectively. but unfortunately, because of thedamages more bridges work in a state of unsafety in recent years. In order to detect thedamages, this paper draw its attention to investigate new method of detection damages on thebasis of literature.This paper’s main investigations and innovations are,(1) This paper proposed a new method which take the response of velocity of dynamicload as the input of "Gaussian-5".Then this paper discusses the feasibility of the method intheory.(2)In order to extend the number of loads, this paper investigate the feasibility to detectthe damages of bridge by taking the response of deflection as input of "Gaussion-4" when theload is more than one.(3) First, this paper analysis the advantages of proposed methods in this paper. Second,in order to improve the this paper discuss the influence of different parameters which isclosely related to the method used to detect damages of bridge in Engineering.(4)This paper draw a section of BEAM188by the characteristics of geometry andmechanics of the measurements of the experimental platform. Then it take, respectively, thefirst mode to fifth mode of natural frequency and the first-order vibration mode as the input ofthe module of optimizing of Ansys to detect the damage of the experimental platform. Theresult would provide the basal simulative date to experimentalize experienment further.
