Development of optical fiber sensing system for measuring rolling force |
| |
| Abstract: | A kind of optical fiber sensor for measuring rolling force is developed. Its sensing header takes on the structure of F P cave. The principle of the sensor is analyzed.The general formulas among reflective light strengh of the optical fiber F P cave and the rolling force are derived. The experiment results show that accuracy at 0.18#%, linear strain sensitivity at 1.2×104#V and resolution at 2.5×10-8 have been achieved. The theory and measurement method of measuring the rolling force are correct and practicable. |
