Lightweight design on truss structure of pipe belt conveyor
In order to save the steel consumption in experience-based design of pipe belt conveyor truss structure,an optimal design method based on Design of Experiment(DoE)was proposed,and used in the steel truss design.The load combinations of the pipe belt conveyor truss were analyzed,and the loads were applied in Ansys Workbench according to the most unfavourable load combinations of the truss to identify the dangerous bars.Multi-objectives Genetic Algorithms(MOGA)was used for multi-objective optimization.The results show that,the overall mass of the optimized truss structure was reduced by 32.8%,resulting in a lighter structure;at the same time,the stress ratios of the bars were increased while stilling meeting the strength and stiffness requirements,and the bar sections were better utilized.
