Abstract: Multi-frequency constrained optimization method for constrained optimization of the
inherent characteristics of the object. On the side of large vibrating screen quality optimized to
ensure the optimal dynamic characteristics of the side of the original structure does not have a
big impact. Geometry and the 2,3 and 4 natural frequencies of the side plates are constrained, after
25 iteration, the overall quality of the final side down 138kg, achieved little change in the inherent
characteristics of the side plates under the premise of reducing the quality and reduce cost.
