| Abstract: | For measurement of lateral vibration acceleration of railway bridges, necessary technical measures should be taken to ensure that the data collecting will not be mixed and overlaid, and setting of the data sampling frequency should also meet the requirements for amplitude precision. In this paper, the matters of attention for selection and utilization of instrument for measurement of the acceleration are presented, and the errors possibly occurring during digital filtering are preliminarily discussed as well. |
