The development of a tire model for the prediction of vertical and drag loads in response to large discrete surface obstacles shorter than the tire footprint length is presented. The tire is modeled as a toroidal membrane with the objective of characterizin g the enveloping properties of the tire. An explicit set of equations is used to calculate the tire footprint in contact with a user specified surface profile, the tire volume, the pneumatic pressure, and the resultant vertical and drag loads at the wheel axle. Tire carcass and bottoming loads are also predicted. The model is designed to be computationally efficient for use with aircraft digital taxi simulations. Model predictions are compared with tire test data for low-speed fixed axle excursions over short rectangular bumps and dips. Excellent quantitative correlation is demonstrated.read more

The development of dynamic taxi design procedures.
TL;DR: In this paper, four forms of dynamic taxi design procedures were developed that consider the three dimensional character of the runway/taxiway surface environment, along with their potential criteria that were adapted to ensure structural integrity, may be categorized as arbitrary, discrete, deterministic and statistical.

TL;DR: In this paper, the development of generalized vehicle-terrain mathematical models of wheeled and tracked vehicles running in hard and soft soil is described, and the computer simulation phase of work is carried to the point of mechanizing 3-degree-of-freedom and 5-degree of freedom models in real time on the analog computer.
