Abstract:
The mechanical properties of the sand of Takelamagan desert in
Xinjiang under moving vehicle are studied by soil dynamic
triaxial test apparatus. The nonlinear elastic constitutive
model of the sand under moving vehicle is established first.
These results lay the foundations for studying the interaction
between vehicle running gear and the sand of Takelamagan desert
in Xinjiang, and developing sand vehicle.
Key words: Vehicle Takelamagan desert sand Constitutive relationship Nonlinear
elastic constitutive model
