摘要

为使动力电池箱底板达到焊接工艺规范要求

通过数值模拟的方法优化其焊接顺序。以某型动力电池箱底板为例

在现有焊接顺序方案下

采用顺序热力耦合法建立其搅拌摩擦焊数值模拟模型

仿真结果表明动力电池箱底板焊接残余应力应变与实际变形结果吻合度高

变形挠度超过工艺规范要求。为此

综合考虑调整焊接顺序以控制残余变形的方法具有简单可行、成本较低等优点

提出5种焊接顺序候选方案

以最大残余变形挠度最小为原则筛选得到优选方案。现场试验结果表明

数值模拟结果与实际结果误差较小

所建立的模型满足要求

且采用优选的焊接顺序方案后

动力电池箱底板焊后最大残余变形挠度较原焊接顺序方案降低了约33%

由4.92 mm减小为3.31 mm

符合底板的焊接工艺规范要求。

Abstract

In order to make the bottom plate of power battery enclosure meet the welding process specification requirements

the welding sequence is optimized through numerical simulation. A certain type of power battery enclosure's bottom plate was taken as the research object. According to the existing welding sequence scheme

its numerical simulation model of friction stir welding was established by adopting the sequential thermal-mechanical coupling method. The simulation results showed that the values of welding residual stress and strain were consistent with the actual ones

and the value of deformation deflection exceeded the specification requirements. As the method of adjusting welding sequence to control residual deformation is simple

feasible and low-cost

it was adopted to propose five candidate schemes for welding sequence. The optimal scheme was selected based on the principle of achieving minimum residual deformation and deflection. Field test results showed that the error between numerical simulation results and actual ones was small

which shows that the established model is satisfactory. By adopting the proposed optimal welding sequence scheme

the maximum residual deflection of the bottom plate was reduced by 33%

decreasing from 4.92 mm to 3.31 mm

which meets the requirements in the welding process specification.
