基于Abaqus的轨道车辆压型件成形模拟系统开发

Development of Simulation System for Rail Vehicle Profile Forming Based on Abaqus

轨道车辆压型件具有尺寸大、板料厚等特点,成形较为困难,成形过程也较为复杂。在使用有限元软件对其进行仿真时,操作过程非常繁琐,且容易出现误操作。基于Python语言,以Abaqus为平台开发了一种成形模拟系统,仅需输入工艺参数即可生成压型件成形分析所需的有限元模型,方便用户快速地建立有限元模型,节省建模时间,并以轨道车辆压型件中的小弯梁零件为例,验证了本系统的实用性与可靠性。

Railway vehicle profiles are characteristic of large size and large thickness,so it is difficult to form and the forming process is complicated.If finite element software is used to simulate its operating process,it is very tedious and easy to misoperate.Based on Python language and Abaqus,a forming simulation system is developed,which is used to establish the requested finite element model for its forming analysis by inputting the process parameters.It is convenient for users to establish the finite element model quickly and save time of the modeling.The practicability and reliability of the system are verified by taking small bending beam parts in rail vehicle compression parts as an example.
