The Simulation of Stem Cutting and Parameter Optimization for Power Station Valve

摘要

We expound the finite element simulation and the key points of metal turning by the material properties of the stem in this paper, and select the proper material constitutive equation, then use the adaptive meshing technique, and then finite element modeling was carried out on the valve stem in the professional finite element software Advantage FEM. The optimization scheme we designed of finite element simulation for the valve stem through the finite element software Advantage FEM, and we research the influence of the amount of feed and speed cutting process about the cutting force and the cutting temperature.
