In rolling, the frame not only need withstand a lot of roll force, moreover when nips the steel and throws the steel, it must withstand the very big impulse.Therefore, to the frame of the strength,stiffness and vibration characteristics re- search is very important,and to ensure the security and stability of the frame. First of all, introduce some of the basic theory of the finite element method and finite element analysis software, to fully understanding the characteristics of various analysis software, combined with the specific requirements of the static and dynamic analysis of the frame, ANSYS is the reasonable selection of the finite element analysis software. Establishes the geometric model of the frame by using the SolidWorks software.Then through the format conversion, will be introduced to large analysis software ANSYS. Carries on the intensity and the stiffness analysis to it, according to the stress analysis cloud chart, discovers the place where makes the most centralized spot of the frame stress.According to the displacement cloud chart, discovers the frame weakest spot, then carries on the intensity and the rigidity examination to it, confirms whether to satisfy requests. Carries on the modal analysis by using the finite element method to the frame, extraction the first ten steps the natural frequency and its corresponding
