| Abstract: | A new method named lantern rings screw thread method, was put forward in order to solve the difficulties in measuring the strain and streamlines distribution during die forging of complex components. This method can not only measure but also analyze quantitatively the deformation of die forging without substituted material. The strain distribution can be obtained, when using the method to analyze the axial strain and the four streamlines of two typical sections during the deformation of a compressor impeller. So it can be used as a reliable experimental method to examine the strain distribution during die forging. |
