In order to improve the road adaptability of heavy-duty logistics AGV robot,an AGV mobile system suitable for logistics storage workshop was designed.A structure of longitudinal arm independent suspension was constructed,and there was also a regulating mechanism to change the shock absorber angle and longitudinal arm length.Based on simplified suspension system support model,the static characteristics were analyzed.A optimization mathematical model was established,in which the different size parameters of the support were taken as variables,the structure mass was taken as the objective function,the maximum deformation and maximum equiva-lent stress were taken as the constraint conditions.Design variables were optimized by using controlled elitist NSGA-Ⅱ algorithm.The strength and stiffness of the optimized structure were checked to meet the use requirements,which proved the rationality of the structural optimization.So the lean manufacturing of components is realized and the utilization rate of materials is improved.
