  • REMOTE SENSING OF TERRAIN STRENGTH FOR MOBILITY MODELING
    Publication number: 20220406056
    Abstract: Methods for characterizing soil stiffness of an area. One example method includes receiving, with an electronic processor, a parameter corresponding to a soil type of the area; receiving, with the electronic processor, a plurality of thermal images of the area; determining, with the electronic processor, an apparent thermal inertia of the area based on the plurality of thermal images; determining, with the electronic processor, a soil gradation of the area based on the parameter; determining, with a machine learning algorithm executed by the electronic processor, an approximate soil stiffness of the area based on the apparent thermal inertia; and outputting, to a display communicatively coupled to the electronic processor, a representation of the approximate soil stiffness.

  • System for virtual prediction of road loads
    Patent number: 7363805
    Abstract: A system is provided for full-vehicle analytical road-loads prediction, which reduces the time and cost of modeling tires and tire-road interface, using road load simulations rather than actual measurements. The system includes a method to perform tire tests in a virtual environment, a road-load tire model for simulations in multibody environments; a tire model for FE simulations; and a comprehensive graphical user interface to support the user in all the steps of the analytical process.
