The present thesis is the result of the efforts devoted to developing the coupling vibration for analysis of trolley bridge structures. When the weight of container is heavier and heavier, the speed of the trolley is faster and faster, and the dynamic response and coupling vibration of the container crane is heavier. Bridge structure coupling analysis of structure evaluation is important dynamic performance. For the axle coupling structure in the high-speed car, the shore bridge structure is huge, and the constraint condition is complex, so it is difficult to carry on the artificial excitation and effectively drive signal measurement. In that case, the traditional the input/output signal recognition method is hard to apply. This paper main research work includes: using the finite element dynamic analysis method and structure dynamic test method, the structure is designed based on the axle coupling under dynamic response data. The structural dynamic characteristics are analyzed by axle-coupled method combined with identification method. According to the dynamic response data, the basic principle of axle coupling method is obtained by the analysis, concentrating in the theory method and dynamic response data acquisition, etc.
