Some theoretical calculation formulae for tensile resistance and shear resistance were derived based on plastic forming principle; then the finite element software Deform was used to numerically simulate the riveting process of 5052 aluminum alloy sheet; and then the verification was carried out by designing corresponding experimental device and riveting experiment under different parameters. The result shows that the simulated neck thickness values“N”and embedding quantities“U”agree well with experimental values;and the tensile resistance and shear resistance from riveting experiment correspond to the theoretical calculation values.
