冲压成型仿真在重载铁路货车下侧门板中的运用

Forming simulation of side door plate for heavy-haul railway freight car

在铁路货车零件的产品设计阶段,采用冲压成型仿真软件对冲压件进行成型仿真,可以验证冲压件的成型性能,为产品设计提供重要依据。以铁路货车大轴重货车的下侧门板为例,在零件的设计阶段,通过对零件进行冲压仿真,预测零件可能出现破裂,通过不断修改产品结构,最终确保零件具有良好的成型工艺性。

The forming simulation applying on sheet metal plate could verify the forming property of piece parts and provided the evidence for product design,when the fright car parts were still on the design stage.Taking side door plate of heavy-haul railway freight car for example,simulation on the parts could predict potential crack at the design process,improve the product structure,make sure that the parts had excellent forming character and avoid the forming deficiency.
