Abstract: The technology of combined sinking-bulging auto- mobile corrugated sleeve is proposed, and the deformation mould is designed. The designed principle is given for determining the bulging elastic meson, the mechanical model for combined necking-bulging corrugated sleeve is founded, and the stress equilibrium equations for deformation zones are deduced. The strain field and stress field is calculated on the basis of the test research.

Key words: Combined sinking-bulging Equilibrium equations, Corrugated sleeve, Strain field, Stress field
