Abstract EN
The resistance force of the granular matter is modeled as a linear superposition of a static (quadratic depth-dependent) resistance force and a dynamic (quadratic velocity-dependent) frictional force.
The impact is defined from the moment the end point of the system comes in contact with the granular matter surface until the vertical linear velocity of the end point is zero.
The variables of interest are the final depth at the end of the penetration phase and the stopping time.
The results for a two-link kinematic chain with two points of contact were compared to the results obtained by applying the resistance force formulation developed to corresponding CAD simulation models.
The results revealed that the final displacement increases with initial velocity, while the stopping time decreases.
The sensitivity to the initial velocity was studied and an improvement to the resistance force formulated as a result.
A series of expressions are proposed for the resistance force coefficients.
