Abstract

The model of QSn7-0.2 sliding bearing in two-pass spinning was established based on the Simufact finite element software. The simulated experiment scheme was built up by the orthogonal experiment method

and the significant degree of influence of the thinning rate

the pass ratio

the one-time feed ratio

the second-pass feed ratio on the deformation uniformity of sliding bearing and the optimal combination of parameters were obtained by the range analysis. Then the optimized parameter combination was verified by the experiments. The results reveal that when the thinning rate is 28

the pass ratio is 5∶5

the one-time feed ratio is 0.8 mm/r

the second-pass feed ratio is 1 mm/r

the sliding bearing after two-pass spinning can have the better deformation uniformity.
