Our Cellular Structures

Extremely rigid, strong and lightweight structures developed through research into cell geometry, orientation, density and material.

25 kg/m track skeleton mass, excluding actuators
11× lighter than conventional rail track
38 shapes recorded in the overview study
< 50% vehicle mass versus comparable vehicles
Strength through geometry

Less material.
Precisely placed.

AALT’s track skeletons, vehicles and supporting structures use purpose-designed cellular structures to achieve high rigidity at exceptionally low mass. Instead of requiring equal strength in every direction, each geometry is matched to the actual static, dynamic and impact loads it will encounter.

Our research compares isotropic and anisotropic cells, solid and hollow struts, cell density and hybrid arrangements. Multiple anisotropic cells can be oriented together so each group carries loads in the directions where it performs best.

Documented study scope

The overview records 38 shapes studied. A separate working comparison report catalogs 36 identified cells and reports 17 as tested. Those figures describe different stages of the research and are shown separately rather than blended into one total.
