【摘要】 在用振动频率法测量索力的过程中,产生波形畸变是不可避免的,通过计算或标定系统频响特性来修正斜拉桥索力检测中波形的畸变,恢复实测波形的幅值和相位,这项研究对准确测量索力具有重要的实际意义,文章以一阶系统为例详细说明波形的修正方法。更多还原

【Abstract】 In the process of measuring the cable power through the vibration-frequency method, distortion is inevitable, but it can be corrected through calculating or labeling the systemic frequency response character in checking-up the cable power of the cable-stayed bridge. In the paper,a one-module system is taken as an examaple to explain the method in detail. This study is of pratical significance for measuring the cable power accurately.更多还原
