原始语种摘要: Because of its characteristics of high operating efficiency and low operating cost, jib crane, mainly used to complete the loading and unloading of cargo and stacking operations, has become indispensable transport equipment on ports and terminals. As the core structural component of jib crane, design of superstructure will affect the stability of machine directly. Based on the unified objective function method, the mathematical model about multi-objective optimal design of superstructure was established which superstructure was served as a whole. Reduction of the maximum of the luffing resistance moment and unbalanced torque, as well as decrease of the fluctuations of hanging point vertical displacement were taken as the objective functions, and the coordinate of the hinge point position,...
