摘要
由拉索的运动方程出发,经推导得到索力与自振频率之间的精确对应关系,探讨了拉索的抗弯刚度、附加质量、垂度、斜度以及边界条件对索力测试结果的影响,研究所得的结论对频率法测试索力具有指导意义。
Start with the relation of motion, the exactly relationship between the cable force and natural frequency of vibration is established. The reflection of the anti-flex stiffness, additive weight, deflection, slope and elastic restriction to cable force are analyzed. The research result has master meaning to the frequency method of cable force measurement.
