With the buffing system as a study object,the multi-target optimal model is built with height difference of hook motion trail during the buffing process,intensity of boom strength,and the difference of buffing hydraulic cylinder forces as targets.The genetic algorithm is used to get the ideal solution and several efficient solutions for the problems,and the preference order for each efficient solution is determined based on the grey clustering method,in order to figure out the optimal solution.The applications show that these solutions for multi-target optimal problems can provide more practical method and reference for decisions,and improve the design reliability and effectiveness.
