| Abstract: | The strain yield locus of the stress yield criterion was advanced and the strain ellipse method for calculating the limit bulging coefficient was given. The idea of matching compound bulging force parameters and the matching principle for hydro bulging automobile axle housings were proposed. The scope of the ratio of longitudinal strain to latitudinal strain was determined. The axle housings for a 0 75 ton automobile was tested and the technological parameters were given for sinking the end part and hydro bulging the central part. |
