Since a garbage disposal line's unloading platform frame which is based on the traditional empiricism design suf-fers from redundant quality,in this article the improved particle swarm algorithm is used to carry out the lightweight research on the unloading platform frame.First,the ANSYS finite-element analytical software is used for the static analysis on the unloading platform frame;then,efforts are made to simplify the unloading platform frame,according to the results obtained from the static analysis;finally,the improved particle swarm algorithm is conducted to explore the simplified unloading platform frame's light-weight design.The optimized unloading platform frame has reduced its weight by 64.16％compared with the original frame,while the requirements of strength and rigidity are satisfied.
