摘要
构架强度对轨道工程车辆的安全性、牵引力及运行品质有重要影响。采用ANSYS Workbench有限元仿真软件,在超常载荷、模拟运营与模拟特殊运营载荷工况下,对一种轨道工程车转向架构架进行静强度、疲劳强度评估计算与模态分析。计算结果表明,构架静强度、疲劳强度及模态满足TB/T 2368-2005《动力转向架构架强度试验方法》和TB/T 1335-1996《铁道车辆强度设计及试验鉴定规范》要求。
The frame strength has an important influence on the safety,traction and operation quality of track engineering vehicles. By using ANSYS Workbench finite element simulation software,based on service conditions including overload,operation simulation and special operation load simulation,the static strength,fatigue strength evaluation & calculation and modal analysis are carried out for the bogie frame a type of track engineering vehicle. According to the calculation results,the static strength,fatigue strength and modality of the frame can meet TB/T2368—2005 Motive Power Units-Bogies and Running Gear-Bogie Frame Structure Strength Tests and TB/T 1335—1996 Specification of Strength Design and Test Evaluation of Railway Vehicles.
