通过对动车组座椅底架的结构分析,并构建简化的力学模型,以底架纵梁的截面面积为目标函数,最大挠度和强度为约束条件,采用优化设计的方法,找到满足挠度和强度要求时,梁截面直径和壁厚的最佳取值点。
Through the analysis of the structure of the chassis frame of the EMU and the simplified mechanical model, the cross-sectional area of the longitudinal beam of the chassis is taken as the objective function and the maximum deflection and the strength are the constraint conditions. The optimum design method is used to find the optimal solution to the deflection and the strength When required, the beam cross-section diameter and wall thickness of the best value points.
