| 摘要 |
The invention relates to an FBG strain sensor for measuring strains to curved surfaces, the fibre (4) being fixed between two securing elements (5a, 5b) whose undersides are designed as adhesive surfaces, the optical fibre (4) and these securing elements (5a, 5b) being embedded in a protective compound (6) which consists of a soft silicone rubber or a plastic that has comparable mechanical properties, and the fibre (4) being embedded between an upper and a lower thin sliding film (7, 8) or a sliding tube (9) that consists of Teflon or of a plastic which has a low friction coefficient comparable to Teflon, the underside of said lower sliding film (7) or the lower external surface-line of the sliding tube (9) lying in a plane with the adhesive surfaces of the securing elements (5a, 5b). |
