摘要：

为深入研究高压气瓶翻板旋压收口成形机理，借助有限元分析软件Deform-3D，对翻板旋压收口成形过程进行了数值模拟研究。模拟分析结果表明：翻板与管坯接触区的金属受三向压应力作用，其塑性良好，在整个成形过程中，等效应力和等效应变速率变化基本一致，其规律是先增大后减小；等效应变基本沿轴向分层分布，且同一层圆周方向上的等效应变大小基本相等。3个旋压分力中，径向分力最大，切向分力稍大于轴向分力。气瓶增厚效果非常明显，最大壁厚值出现在瓶颈过渡处（此处内部易产生褶皱）。采用自行设计制造的610热旋压机进行了气瓶旋压收口试验，试验结果与模拟结果相吻合。

In order to further research the neck-spinning mechanism of the high-pressure tank plate, its neck-spinning process was simulated by the FEM software Deform-3D.The simulation results show that the deformed metal in the contact zone between the tube and the plate is in a 3D compressive stress state, and the plastic state is very good. In the whole forming process, the changes of the equivalent stress and equivalent strain rate are both basically consistent with the trends that first increase and then decrease. The equivalent strain substantially distributes along the axial stratification, and the equivalent strain on the same layer circumferential direction is essentially equal. Among the three components of spinning force, the radial component is the largest, and the tangential component is slightly larger than the axial component. Cylinder thickening effect is very obvious, and the biggest thickness value appears on the bottleneck transition, where wrinkles are prone to occurring. The neck-spinning test of the tank was operated by self-designed 610 hot spinning machine. The test results coincide with the simulation results.
