Effects of grouser movement to sand-grouser interaction on unconsolidated soft sand incline using discrete element method (DEM) simulation by Siti Suhaila, Sabarudin, Ahmad Najmuddin, Ibrahim, Ahmad Shahir, Jamaludin, Fukuoka, Yasuhiro

“…Typically, a rover is equipped with fixed grousers on its wheels (conventional grousers). A problem that usually occurs by using conventional grousers is the rover getting stuck on an unconsolidated sandy dune incline as the wheel tends to slip and sink into the sand. …”

2D simulation of assistive grouser mechanism using discrete element method (dem) for traversing on unconsolidated soft sand by Siti Suhaila, Sabarudin

“…This simulation was divided into three phases, Phase 1 simulates multiple fixed and assistive grousers attached to a wheel (Conventional Wheel - CW 80 mm and Assistive Wheel - AW 90 mm), Phase 2 simulates a single fixed and assistive grouser attached to a wheel (CW 20 and 80 mm, AW 50 and 90 mm), and Phase 3 simulates a single assistive grouser with different sinkage length (10, 20, 30 and 40 mm) and grouser angle of attack (0 and 30-degree). …”
