Combining with displacement sensor

measuring device and method of cable force based on elastic deformation is proposed; introduce structure and principle of the system; and then obtain datas of cable force and cable variable which are corresponding to cable force datas through calibration

loading experinment and filtering;finally

through data fitting analysis

obtain linear relationship between cable shaped variables and values of the cable force

at the same time

it is validated. When cable force measurement range of 5

20 k N and measurement frequency is 1 Hz

the maximum measurement error will be controlled within 10 %

average error of measurement is about 5 %

and with increasing of cable force measurement under test

measurement precision is increased.
