Abstract：

In order to design the body of cold forging press more reasonably and make it be of antivibration, safety and reliability, taking CWFP 12500 kN cold forging press designed by BRIMET as an example, the natural frequency of cold forging press body was calculated by using finite element analysis software ABAQUS firstly.Several improved programs,whose finite element analysis was carried out separately,were put up and compared with analysis result of original body. The 3D model of body was drawn by using SolidWorks. And then,the improved programs, whose affected factors were verified and analyzed, were analyzed by using software ABAQUS again. The verification shows that using reinforcement plate in the key parts of body is the most important factor for affecting the natural frequency of body.
