【Abstract】 Interference-fit technology can improve structure joint strength. For composite structures, the key of interference-fit technology is to control interference. Normal riveting can not produce well-distributed interference, so it can not be used to make interference-fit riveting of composites. we point out that electromagnetic riveting can make interference-fit riveting of composites, and that appropriate washer can limit expand of rivet, appropriate gap between rivet and hole can reduce interference. The appropriate configuration of washer and the gaps are presented. The experiments show that electromagnetic riveting technology can achieve interference-fit riveting of composite structures.更多还原
