ANSYS analysis for mobile gantry crane's optimization design in packing machinery field

Mobile gantry crane at work mainly by concentrated load, therefore it is very important for the structure optimization and checking. In this paper, in order to compare before and after the optimization of the same size and shape of different mobile gantry hanger, the situation of deformation and stress before and after the first was optimized by using UG software to move the gantry crane made a 3D modeling, and then using the finite element software ANSYS to analysis the two kinds of structure at work status, this paper compares and analyzes intuitively reflect the structure of the two kinds of deformation and stress distribution. Analysis results show that when the concentrated load is 100, the maximum structure before and after optimization were 0.217 e8, 0.212 e8, minimum value of 99152.4, 63716.8, respectively. Analysis shows that the optimized structure, in the same size of concentrated load, maximum stress and minimum stress are smaller, deformation and far less than optimization of the structure of the former.
