【摘要】 将具有一定几何断面形状的型材或条形钢板经专用成形设备卷曲成形，通过切割、焊接工艺技术，生产环形件。为减少切削加工，对原始坯料断面形状，采用有限元分析的方法确定。更多还原

【Abstract】 It is introduced to produce ringlike parts by coiling and deforming the steel strip orother materials with some geometric section with special deformation equipment and then cUtting andwelding. The finite element method is used to determine the section shape of the material to reducecutting working.更多还原
