| Abstract: | Using the FE parametric quadratic programming method based on the parametric variational principle,3-D elastic-plastic precise analysis of the supercharger compressor impeller is conducted,its residual strains in the process of pre-overspeed manufacturing technology is computed,and the distribution laws presented with the computed results well agreed with the tested ones. |
