Do lunar rover wheels sink equally on Earth and Moon?
Results in Physics, 2019 There has been a long discussion on how the low-gravity effects that LRUs (Lightweight Rover Units) on the Moon will experience, can affect mission planning and surface operations.

Neural network based terramechanics modeling and estimation for deformable terrains
CoRR, 2020 In this work, a neural network based terramechanics model and terrain estimator are presented with an outlook for optimal control applications such as model predictive control. Recognizing the limitations of the state-of-the-art terramechanics models in terms of operating conditions, computational cost, and continuous differentiability for gradient ...

Dynamic simulation on vibration control of marching tank gun based on adaptive robust control
Journal of Low Frequency Noise, Vibration and Active Control, 2020 In order to better understand the dynamic behavior and decrease the muzzle vibration of marching tank, a mechanical–electrical–hydraulic integrated dynamic model of marching tank was established based on a novel dynamic co-simulation method.

Modelling of Truck Tire–Rim Slip on Sandy Loam Using Advanced Computational Techniques
GeotechnicsVehicles often experience low tire pressures and high torques in off-road operations, making tire–rim slip likely. Tire–rim slip is undesirable relative rotation between the tire and rim, which, in this study, is measured by the relative tire–rim slip ...
