Terramechanics based Traction Prediction for Lunar Rover by High-Speed Granular Scaling Law

The development of lunar rovers requires research in terramechanics to understand the interactions between wheels and loose terrain. While extensive terramechanics research has been conducted on Earth, few studies have focused on adapting these findings to the Moon’s different gravity environment. This project will focus on the Granular Scaling Law (GSL), a recently utilized mechanical similarity law, and discuss its application to terramechanics. In particular, considering both rover speed and gravity is essential for this application. The host laboratory has world-leading expertise in low-gravity experimental techniques, while the home laboratory is at the forefront of developing experimental facilities for high-speed traversal on lunar terrain. By combining these complementary technologies, this project aims to address the previously unexplored application of the GSL in terramechanics and conduct precise performance predictions for lunar surfaces. If successful, this project is expected to yield significant theoretical insights for both laboratories and contribute greatly to the future development and control of rovers in both countries.
