Abstract In order to explore the properties and the optimization method of IHI flying shear mechanism, This paper analyzed the structure and working principle of IHI flying shear mechanism. The analytic method formula of the position of shear mechanism through numerical method was deduced and the initial position of the shear mechanism was calculated. The reappearance of the movement process of flying shear occurred in simulation analysis based on the rod model of flying shear mechanism which was established by using the ADAMS dynamics analysis software. And the shear blade motion trajectory, velocity curves and shear edge opening curves were obtained from it. According to the analysis results, the structure can be optimized through the software of ADAMS. The optimization results improve the problems of ahead and lag of the cutting speed in the cutting process which is beneficial to the shearing process and rolling process. Analysis and optimization results of ADAMS have practical application value for the structure design and transformation of IHI flying shear mechanism.
