摘要： A method of shaping a metallic honeycomb panel using a continuous drive sheet. The metallic honeycomb panel may have a perforated upper sheet, a non-perforated lower sheet, and a metal honeycomb core fixed between the upper and lower sheets. The method may include the steps of designing and manufacturing the drive sheet using finite element analysis (FEA) and criteria regarding shaping of the metallic honeycomb panel, then welding the drive sheet to the lower face of the lower sheet. The drive sheet may cover all of the lower face of the lower sheet and may have varying thicknesses determined based on the criteria and the FEA. The method may also include the steps of heating the drive sheet and metallic honeycomb panel to a creep forming or hot-stretch forming temperature and urging the metallic honeycomb panel and drive sheet into a male or female die mold to be shaped.

摘要翻译：使用连续驱动片成形金属蜂窝板的方法。金属蜂窝板可以具有穿孔的上板，未穿孔的下板和固定在上板和下板之间的金属蜂窝芯。该方法可以包括使用有限元分析（FEA）和关于金属蜂窝板的成形的标准来设计和制造驱动片的步骤，然后将驱动片焊接到下片的下表面。驱动片可以覆盖下片的所有下表面，并且可以具有根据标准和FEA确定的变化的厚度。该方法还可以包括以下步骤：将驱动片和金属蜂窝板加热至蠕变成形或热拉伸成形温度，并将金属蜂窝板和驱动片推入待成型的阳模或阴模模中。
