In the rolling process, the material undergoes plastic deformation due to flow stresses caused by the roller pressure. In this article, first, the process of cold rolling of compressor blades was studied by means of experimental testing and simulation utilizing deformable rollers. Then, the pressure distribution on the blade's surface was investigated during the rolling process. The results show that the pressure distribution is not assumed as a known common hill shape, but depends totally on the caliber section. The highest values of pressure are associated with areas close to the edges of the section which are affected by more reduction and stress, and thus, the surface pressure diagram changes to a saddle shape distribution. The simulation and experimental results are calculated and compared showing a good agreement.View full textDownload full textKeywordsBlade, Cold, Compressor, Distribution, Pressure, Rolling, Simulation, ThinRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10426914.2011.560229
