Truss robot has strong handling ability,convenient operation and high positioning accuracy,and plays an extremely important role in the manufacturing industry.Aiming at the problems of poor operation stability and material redundancy caused by the self-weight of the truss robot,the structural optimization design was studied.At present,the structure optimization design of truss robots has a large number of finite element simulation calls,large time loss,and low optimization efficiency.In order to solve this problem,after analyzing the relationship between size,load,stress and deformation of truss robot beam components,a structural optimization design method based on Kriging model and PSO particle swarm algorithm was proposed,which can effectively reduce the number of finite,element simulation calls,save time and improve the optimization design efficiency.
