Zeinab El-Sayegh, PhD, PEng, Department of Automotive and Mechatronics Engineering, Ontario Tech University, will introduce the concept of virtual soil moisturization and its impact on the performance of 315/80R22.5-sized truck tires. The truck tires are simulated using multiple layers and materials in a Finite Element Analysis (FEA) environment. Moist sand, composed of layered water and sand particles, is simulated using the Smoothed-Particle Hydrodynamics (SPH) technique. The tire-sand interaction is defined by a hybrid FEA-SPH interaction model, and the tire's tractive performance—including tractive effort, motion resistance coefficient, and tire sinkage—will be presented. Finally, the challenges of validating such models will be discussed, along with future work on developing more advanced tire-terrain models.

April 25, 2024 | Dan Negrut, Ph.D., Terramechanics Models for Lunar Robotics Applications
Dan Negrut, NVIDIA CUDA Fellow, Bernard A. and Frances M. Weideman Professor of Mechanical Engineering, Simulation-Based Engineering Lab, University of Wisconsin-Madison. Our lab has worked on several projects aimed at improving the mobility of autonomous rovers operating in lunar conditions. The design of such rovers increasingly relies on computer simulation. The talk will cover two main topics: it presents an overview of terramechanics models in robotics, and it briefly describes the sensing used in lunar mobility simulations.

Christopher Goodin, Ph.D., Center for Advanced Vehicular Systems, Mississippi State University, will introduce the MAVS and show some examples of how it is being used in the classroom as an instructional tool for autonomous vehicles, by graduate students for research, and by researchers around the world in a variety of military and commercial applications. The technical underpinnings of the MAVS will also be presented.

Mohit Nitin Shenvi, Ph.D., Terramechanics, Multibody, and Vehicle Systems Laboratory, Virginia Tech: This talk focuses on the literature of snow characterization and on an analysis performed to identify the extent to which testing conditions affect the traction coefficient of tires using the ASTM 14-inch Standard Reference Test Tire (SRTT) on snow. Another area of focus will be the performance evaluation of an custom in-house device against the Clegg impact hammer and CTI penetrometer when employed in the field for measurements on a compacted snow test track at the Smithers Winter Test Center.

Paweł Tomiło, Ph.D., Lublin University of Technology. The session will introduce the hybrid-locomotion rover concept. The design of a hybrid robot combines the characteristics of wheeled and legged robots. The rover is equipped with a crawling mechanism that will allow it to climb steep slopes areas where a wheeled vehicle could slip due to loose ground. The concept of the rover will be discussed, the current state of research, and future work on the development of the rover will be presented.

RECORDING | TERRABITE — The 11th Asia-Pacific Regional Conference of the ISTVS was held online in September 2022, hosted by the Harbin Institute of Technology, PR China, and included presenters from around the world. The Conference Committee identified papers whose authors were encouraged to submit manuscripts for a Special Issue of the Society’s Journal of Terramechanics. The Special Issue that resulted represents a selection of the best papers of the conference: Best Papers of 11th Asia-Pacific Regional Conference of the ISTVS. ISTVS has been hosting online events for ongoing and recent research on terramechanics and terrain-vehicle systems under our Digital Event Series since 2021. Recordings from the series are posted to our YouTube channel. Please join us in two upcoming sessions dedicated to the best papers from this Special Issue. This first session is on February 1.
