[Abstract]:The analysis of energy consumption and carbon emission of machine tool shows that the moment of inertia of spindle is one of the important factors that affect the energy consumption and carbon emission of machine tool. Considering the influence of bending moment and shear force on the stiffness of spindle, the maximum stiffness and minimum moment of inertia of machine tool spindle are taken as the optimization objectives, and the load deformation such as strength, stiffness and torsion are taken as the constraint conditions to establish a high quality oriented machine tool. The multi-objective optimization model of machine tool spindle with low carbon is solved by multi-objective evolutionary algorithm NSGA- 鈪，
