Abstract:
The cold shrink assembly process of shoulder bushing parts has been selected as the research object in this paper, and the finite element software ABAQUS has been adopted to simulate and calculate to research the relationship and variation law between the he shrinkage of the inner diameter of
\phi64 mm shoulder bushing. Then based on the simulation analysis, the regression calculation formula of the shrinkage of the inner diameter of the cold shrink assembly of the
\phi 34 mm shoulder bushing was fitted and verified by experiments. The results show that the error of the calculated value of the shrinkage of the inner diameter of the cold shrink assembly of the
\phi 34 mm shouldered bushing is less than 13%, and the tolerance zone of the shouldered bushing of this type is successfully adjusted in the actual processing and assembly, which reduces the risk of supplementary processing.
