电力蓄电池工程车转向架部件建模与分析

Modeling and Analysis of Bogie Components of Electric Battery Engineering Vehicle

随着电力蓄电池工程车的运行里程增加,其出现的故障问题也越来越多,如走行部转向架等关键部件出现金属疲劳、机械裂纹等情况,严重影响行车的安全性。使用三维软件Solidworks对电力工程车转向架构架进行建模,依据TB/T 2368-2005《动力转向架构架强度试验方法》与TB/T 1335-1996《铁道车辆强度设计及试验鉴定规范》计算构架载荷情况,选取由超常载荷组合的4种工况进行研究,利用Ansys Workbench平台模拟受力分析,获得该部件最薄弱的地方为横梁与侧梁连接部位和构架上一系悬挂安装座两个位置,利用该分析结果,通过技术文件优化、作业流程优化等形式应用于实际作业中,多维度确保机车转向架构架状态良好。

With the increase of the mileage of electric battery engineering vehicle,its failure problems are more and more,such as running bogie and other key components appear metal fatigue,mechanical cracks and so on,seriously affect the safety of driving.The threedimensional software Solidworks was used to model the bogie frame of electric engineering vehicle.The frame load was calculated according to TB/T 2368-2005"Strength Test Method of Power Bogie Frame"and TB/T 1335-1996"Specification for Strength Design and Test Identification of Railway Vehicle".Selection consists of four kinds of exceptional load combination condition,the stress analysis of Ansys Workbench platform simulation to obtain the weakest part of the unit for connection parts and frame beam and side beam on a suspension bridge two installation position,using the analysis results,optimization,process optimization,through technical file used in the actual operation,multidimensional ensure that the locomotive bogie frame is in good condition.
