[0045] 1. Main Application:

[0046] Air transport container pallets are used for containerized air transport of aviation units, solving the problem of bulk material containerized air military transport support and improving the efficiency of air military transport support. They have the capacity to containerize various bulk materials and piece goods, and can be used for forklift, hoisting and slide rail loading and unloading operations.

[0047] 2. Main performance parameters:

[0048] Dimensions: 2235mm×2743mm×58mm (length×width×height);

[0049] Rated load: 4500kg.

[0050] 3. Weight reduction design ideas:

[0051] The general principles of weight reduction design:

[0052] (1) The overall dimensions, mooring ring dimensions, and frame serration dimensions do not change;

[0053] (2) Reduce the overall weight as much as possible without reducing the load index;

[0054] (3) Fully consider the three actual use conditions of pallet lifting, fork loading and roll-on / roll-off.

[0055] (4) Material costs, construction costs, and process routes should be controlled as much as possible, and the construction process must be able to be transformed into mass production.

[0056] 4. Weight reduction design:

[0057] The improved overall structure consists of a frame assembly, an upper skin, a lower skin, and a core layer.

[0058] The outermost edge is a rectangular frame component, the upper skin and the lower skin are fixed on the upper and lower surfaces of the frame component respectively, the core layer is filled in the inner cavity of the frame component, and a total of 22 system rings are installed on the outer side of the frame.

[0059] The frame components are improved from aluminum alloy to fiber-reinforced resin-based composite materials, the upper and lower skins are improved from aluminum alloy to fiber-reinforced resin-based laminates, and the core layer is improved from balsa wood to a rigid cross-linked closed-cell structural core layer.

[0060] While the overall dimensions and functional performance indicators remain unchanged, the lightweight improvement needs are achieved and the corrosion resistance and internal bonding performance are improved.
