Abstract:
Through the analysis of the mechanical and economic influence of the design parameters on the medium and small plane steel gate,the quantitative index formula of the influence degree is established. The formula includes the stress,deformation and weight into the quantitative system. Finally,the influence coefficient values of the panel thickness,the height and the spacing of the main beam are obtained by using the finite element analysis method. The study shows that the height of the main beam has the greatest influence on the comprehensive performance of the gate,which should be considered more in the structural design and optimization.
