摘要: A washer is a common structural element that directly used along the loading path of bolted connection. Pre-load on connection impacts its load bearing capacity and pre-load monitoring an important aspect health (SHM). With change connection, force will and, therefore, outer diameter circumferential length change. Taking advantage high sensitivity small size Fiber Bragg Grating (FBG) sensor, we propose innovative smart encircled by FBG sensor can measure strain washer. For protection, embedded in pre-machined groove surface theoretical approach to derive linear relationship between applied To validate functionality FBG-enabled for situ bolt monitoring, simple but effective testing apparatus designed fabricated. The involves bolt, washer, metal plate, nut. has axial direction precise measurement. calibrated measuring experiments washers are conducted. Experimental results reveal wavelength encircling Both analytical experimental demonstrate proposed novel sensitive monitor real time looseness entire range.
