提出了一种嵌入于多任务提交管理工具框架中的基于网格投影约束的快速自动定位方法． 在当前工序提交求解器计算之前，利用前一工序生成的真实成形结果替代初始板料，调整当前工序中工具与板料之间的位置关系，从而使工具获得理想的初始定位． 与其他多工序数值成形模拟过程所用的定位方法相比，该方法计算时间短，稳定性好，且不影响计算结果的精度，并能有效地解决在数值模拟过程中碰到的带有垂直壁的工具引起的定位问题． 通过某汽车侧围的多工序成形数值模拟，验证了文中方法的可行性．

Proposed in this paper is a fast automatic positioning method based on the constrained projection of meshes,which is embedded in the framework of multi-job submitting system.In order to get a more accurate initial position between the sheet and the tool,the real forming result of the previous stage is utilized to replace the initial sheet to adjust the tool position before the current stage is submitted to the solver.As compared with some other positioning methods for multi-stage simulation,the proposed method is of low time cost,good stability and high positioning accuracy,and it effectively solves the positioning problem caused by the vertical wall of tools.Simulated results of the multi-stage forming process of an automobile body demonstrate that the proposed method is feasible.
