摘要
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。
By EMU seat chassis structural analysis,and build a simplified mechanical model,to and use the cross-sectional area of longitudinal beam chassis as the objective function,maximum deflection and intensity of constraints,using optimal design method,to find the deflection and strength to meet the requirements when the beam diameter and wall thickness of the best data points find best data points of beam diameter and wall thickness when deflection and strength to meet the requirements
