Finite element analysis on the rolling-mill housing of the dry-powder-embedded Zinc-air battery plate forming equipment

Rolling mill is the important component of the dry-powder-embedded zinc-air battery plate forming equipment. The analyses of stiffness and strength character of the rolling-mill housing are done with ANSYS10.0 in this paper. After the calculation we got the stress distribution and deformed state of the rolling-mill housing. Comparing with the admissible stress of the material, mill housing can meet the strength standard under the integrative effectiveness of various loads. In this paper, after founded the model with parameter, using the distortion results and allowable stress as inhibit condition, the main dimension as design variable and the minimum of volume as goal function, the rolling-mill housing optimization design has been made. After the optimization, the rolling-mill housing longitudinal amount of deformity reduced 15%, biggest principal stresses reduced by 24.1% and rolling-mill housing volume reduce by 9.13 %.
