Abstract: Aiming at the problem of heavy weight and excess mechanical properties of double column stacker, a certain type of double column stacker was taken as an example,and the stacker gantry structure was optimized, so that the overall performance of the stacker could be optimized. Firstly, the Workbench was used to simulate and analyze the double column roadway stacker, and the stress and deformation of the stacker under rated load were obtained. Then, the first six natural frequencies and deformation of the stacker under noload condition were calculated by modal analysis, and the points to be optimized in the mechanical structure were identified. Finally, based on the above analysis, through parametric modeling, taking the gantry structure of the stacker as the optimization object,and the stress, deformation and overall quality of the gantry structure as the optimization objectives, three optimization schemes were proposed; the optimal scheme was selected according to the actual needs of the project. The results show that the maximum stress and deformation of the optimized stacker are respectively increased by 4.82% and 9.02%, while the strength and stiffness are still within the allowable range, and the weight is reduced by 9.83%, which realizes the lightweight of the stacker and improves its operation stability and service life.
