摘要:
轴桥作为轻轨列车关键承载部件之一,其结构强度直接影响着列车的运行安全。以某轻轨用独立轮轴桥为研究对象,对其进行参数化建模,分析轴桥在各载荷工况下的受力和变形情况。选取最大等效应力和变形为目标函数,结构几何尺寸为变量,基于响应面的试验拟合法,通过拉定超立方抽样抽取一定数量的样本点进行参数灵敏度分析。结果表明,在所选择的参数变量中,轴头宽度和翼板厚度对轴桥的变形与应力影响较灵敏。计算结果可为轴桥结构优化设计提供参考。
Abstract:
 The axle-bridge is one of the key bearing components of the light rail train whose structural strength directly affects the safety of the train. The independent axle-bridge for a certain light rail train as the research object, was parametrically modeled to analyze the stress and deformation of the axle-bridge under different load conditions. The maximum equivalent stress and deformation was chosen as the objective function and the structure geometry size as a variable. Based on the response surface method (RSM), Latin hypercube sampling (LHS) was used to select a certain number of sample points for parameter sensitivity analysis. The results showed that the breath of axle head and thickness of flange significantly influenced deformation, as well as stress, in the selected parameters, providing a reference for the axle-bridge optimization design.
