| Abstract: | As force-deformation of pre-stressed frame for forging press is rather complex,analysis and calculation on frame force and deformation by using conventional methods has many limitations. An improved calculation method combining with the calculation results of 3 -D contact FEM has been presented,which has reference value in researching and analyzing of frame force and deformation of forging press. |
