摘要
Manufacturing processes including cutting, grinding, polishing, and riveting in metal structures involve dynamic processing loads, which can seriously affect material quality - for example, short transverse stresses or defect densities surrounding rivet holes. In structural health monitoring, these process loads are often not considered when designing loads and usage monitoring sensing and data interrogation systems. Riveting operations for assembling aerostructures and their effects on local material/part quality in the neighborhood of the holes are examined herein. Physics-based nonlinear dynamic models taking into account complex double riveting impacts at the front and back of a fuselage section and the effects of operator preload are first developed to guide the experimental measurement process. Experimental shock acceleration data on the end of a rivet gun are then utilized to extract features for assessing rivet fitness in situ using vibration signals. A qualitative agreement between the analytical and experimental nonlinear resonance data surrounding 100 Hz is obtained. It is demonstrated using rivet quality assurance indicators based on spectral transmission through the tool-part interface and human operator specifications that such techniques can be utilized to identify riveting processes with skewed delivery (gun or bar), circular indentations, and bucking bar slip to assess susceptibility to future damage in fuselage structures. A simple method for normalizing loads data to take into account changes in rivet gun mass is also proposed.
