【Abstract】 The vibration characteristics of railway track is studied in this paper. With an infinitely long beam (which includes the roadbed) on point supports as the track’s dynamic linear response model, the analytic solution of the dynamic response can be obtained, and the free vibration frequency of the track is calculated by the method of transition matrix.更多还原
