The modification technique of the principle of least squares for the tension of cables |
| |
| Abstract: | In the course of tesing technology on line, owing to the frequency error, especially due to the curve rigidity effect, the calculated tension of cables has some errors. This paper introduces the method for correcting the tension of cables by using the principles of Least squares, and it also analyses its accuracy. The results verify that the modificatory technology of the natural frequency is right;the tension of cables accuacy is better and the cables are safe. |
