ln view of the problems of heavy loading, uneven distribution of stress and large local-stress value on the drum
body of high-speed latex disc-separator, the multi-objective optimization method was applied to improve the structure
parameters and stress distribution. By ANSYS parametric modeling, the finite element model on latex separator drum
was created to analyze the force and constraint of the drum, and the contour figures of stress and the strain on the drum
body were achieved. The drum diameter R1, height H1, the cylinder wall thickness Di and bottom thickness D2 were set
as the target parameters. The structure optimization was conducted by using the multi-objective optimization design
method. The optimization result shows that: R1, Hi and Di is respectively reduced by 4.180, 3. 640 and 2. 353 mm,
and D2 increases l.518 mm, and the maximum equivalent stress is reduced by 21. 09 MPa with the decline rate of 4.
29%. The maximum local-stress is decreased, and the total quality is reduced by l.042 kg with the decline rate of 5.
85%. The maximum deformation decreased 0.001 35 mm, and the decreased rate is of 0.65% , and basically reached
the optimization goal. The results and analysis method can provide more guidance and reference for the structure
optimization of disc-separator. |
