此外， 本实施例中， 二维骨架零部件制作过程中， 可将铝合金平面板 材切割成具有插接槽的二维骨架零部件， 使得加工后的各二维骨架零部件 相互之间可插接连接， 以保证二维骨架组装的便利性和稳定性， 保证组装 的三维骨架牢固可靠。 具体地， 在将二维骨架零部件组装成三维骨架时， 可将水平板和竖直板对插形成互相垂直结构的骨架， 同时， 骨架之间连接 可釆用焊接形式， 以保证组装得到的三维骨架的强度。
图 10为本发明实施例中三维蒙皮制作流程示意图。 本实施例中， 如 图 10所示， 上述图 8的步骤 103 中， 釆用小曲面无模成型工艺制作铝合 金材料的三维蒙皮具体可包括如下步骤：
步骤 1021、在三维模型中将三维蒙皮模型分割成适合成型机大小的蒙 皮零部件； 步骤 1022、 利用成型机将铝合金蒙皮材料压制成蒙皮零部件； 步骤 1023、 将压制得到的各蒙皮零部件组装成三维蒙皮。
本实施例中， 三维骨架制作过程中， 首先， 可将设计好的图紙直接输 入数控机床， 将铝合金平面板材切割成所需形状和结构的二维骨架零部 件， 并将切合完成的二维骨架零部件组装成三维骨架， 同时釆用焊接方式 将各二维骨架零部件连接固定； 其次， 在利用小曲面无模成型工艺制作铝 合金材料的三维蒙皮时， 可釆用 3mm厚的铝合金板作为原材料， 在三维 蒙皮模型中将三维蒙皮模型图紙分割成适合成型机大小的几块蒙皮零部 件模型， 并找出蒙皮零部件的内表面和外表面， 输入无模成型机中， 同时 输入蒙皮零部件的厚度， 调整回弹系数和成型点数， 将铝合金板材料压制 成型， 得到各蒙皮零部件； 最后， 可将压制成型的各蒙皮零部件组装在三 维骨架上， 釆用焊接的形式将各蒙皮零部件焊接连接， 并将整个三维蒙皮 焊接在三维骨架上。 可以看出， 本实施例中， 三维骨架和三维蒙皮制作工 艺简单， 各零部件成型容易， 同时， 三维骨架和蒙皮均釆用铝合金材料， 使得整个司机室的重量较轻， 提高了整个列车的承载能力， 且具有较高的 强度。
本实施例中， 三维蒙皮制造中釆用的铝合金材料为可焊接铝合金， 不 但可保证各蒙皮零部件之间的焊接性能， 还可有效保证整个司机室的防腐 性能。 具体地， 本实施例中釆用的铝合金材料符合欧洲标准，材料表如下：

综上可以看出， 本实施例通过釆用多个二维骨架零部件组装得到三维 骨架， 使得三维骨架的制造简单， 可有效降低整个司机室的制造成本； 本 实施例通过釆用多个蒙皮零部件焊接形成三维蒙皮， 使得三维蒙皮的制造 简单， 进一步地降低了整个司机室的制造成本； 本实施例三维骨架和三维 蒙皮均釆用铝合金材料， 使得整个司机室的重量轻， 可有效提高整个列车 的承载能力。 本实施例方法工艺简单， 制造容易， 可有效降低磁悬浮列车 的制造成本， 提高磁悬浮列车的承载能力， 有利于磁悬浮列车的推广和应 用。
最后应说明的是： 以上实施例仅用以说明本发明的技术方案， 而非对 其限制； 尽管参照前述实施例对本发明进行了详细的说明， 本领域的普通 技术人员应当理解： 其依然可以对前述各实施例所记载的技术方案进行修 改， 或者对其中部分技术特征进行等同替换； 而这些修改或者替换， 并不 使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
