Abstract
In this paper, for turning the inner ring groove of a large nuclear cylindrical shell, based on requirements of machining condition, the matching tool assembled are designed. Based on the platform of finite element simulation analysis, the deformation and stress analysis of the tools overall structures are carried out, this provides a theoretical basis for the static strength evaluation of the tools. Through the dynamics modal analysis of the tools, natural frequencies and modal shapes of the tools are obtained, this provides a theoretical basis to evaluate the dynamic characteristics of the tools, in particularly, the resonance characteristics. Through static and dynamic analysis, the reasonableness of structural design of the tools is evaluated theoretically.
