What is Investigation of Effect of Assistive Grouser Attack Angle When Moving in Unconsolidated Soft Sand Inclination Slope Using Discrete Element Method (DEM) Simulation about?

Assistive grouser is an alternative grouser purposed by previous researchers that were used to help wheel rover to improve its performance especially when traversing on unconsolidated soft sand inclination slope. When using a normal grouser (conventional grouser), as the wheel rotates, the grouser pushes the sand particles under the wheel upward and toward the back of the wheel, and causing the wheel to get stuck into the sand surface as the wheel starts digging the sand. But by attaching the assistive grouser, it helps to minimize the subsequence sinkage. Assistive grousers are able to adjust its angle of attack when penetrating into the sand slope surface. Assistive grouser produces horizontal traction force that is similar to the bulldozing movement concept. When assistive grouser moves, it enters and exits sand surface without moving a large amount of sand particles from below of the wheel toward the back of the wheel and prevent the wheel from the stuck phase. From the previous experiment, by using assistive grouser with adjustable angle, it helps to improve the performance of wheel rover in term of minimizing the sand movement from under the wheel when the wheel rotates, less
