Tire‐Pavement Contact Stress Characteristics and Critical Slip Ratio at Multiple Working Conditions

Advances in Materials Science and Engineering, Volume 2019, Issue 1, 2019., 2019
The contact stress distribution of tire‐pavement is generally assumed to be uniformly distributed in circles or rectangles in the pavement design. This simplification can solve some common engineering problems, but it neglects two factors including magnitude and direction of the contact stress.

Motion Predicting of Autonomous Tracked Vehicles with Online Slip Model Identification

Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016
Precise understanding of the mobility is essential for high performance autonomous tracked vehicles in challenging circumstances, though the complex track/terrain interaction is difficult to model. A slip model based on the instantaneous centers of rotation (ICRs) of treads is presented and identified to predict the motion of the vehicle in a short ...
