摘要
为了快速完成铁路货车转向架构架的虚拟疲劳试验,提出了一种采用LMS平台基于UIC510-3标准的疲劳试验仿真方法。首先对转向架构架进行有限元建模,依据UIC标准确定边界条件;其次通过模拟在超常载荷工况下的静态承载载荷,对其结构静强度进行评价;最后模拟车辆在主要运营工况下的动态循环载荷,运用LMS平台进行疲劳试验仿真及评价。计算结果表明:该转向架构架具有良好的抗疲劳性能,其疲劳性能满足设计要求。该方法对轨道交通装备的疲劳性能的预测有较好的应用价值。
In order to rapidly realize the virtual fatigue test for welded bogie frame,with the help of LMS platform,a fatigue sim⁃ulation test method based on UIC510-3 standard is proposed.Firstly,the bogie frame is modeled by finite element method,and the boundary conditions are determined according to UIC standard.Secondly,the static strength of the structure is evaluated by simulating the static load under the extraordinary conditions.Finally,the dynamic cyclic load of the rolling stock under the main operating conditions is simulated,and the fatigue test simulation and evaluation are carried out using the LMS platform.As the calculation results shown,the bogie frame has good fatigue resistance and its fatigue performance meets the design require⁃ments.This method has a good application value for the fatigue performance prediction of rail transit equipment.
