Using the optimization method, taking the lightest weight of the crane as the objective function, taking the cross-sectional dimension of the main beam as the design variable and the strength and stiffness as the constraints, the finite element analysis software MSC / NASTRAN is applied to the gantry crane metal structure Structural optimization. Through optimization and analysis, the optimal design parameters of the main beam components of the crane structure are obtained, and the design is effectively improved
