Wave control of a flexible space tether based on elastic metamaterials
International Journal of Mechanical System Dynamics, 2023 This study proposes a spider‐web elastic metamaterial to suppress vibrations in space slender structures, such as flexible space tethers. The metamaterial consists of unit cells that are periodically distributed on the space tether to obtain band gaps ...

GAMM-Mitteilungen, Volume 46, Issue 1, March 2023., 2023 Abstract Compared to conventional robots, flexible manipulators offer many advantages, such as faster end‐effector velocities and less energy consumption. However, their flexible structure can lead to undesired oscillations. Therefore, the applied control strategy should account for these elasticities. A feedforward controller based on an inverse model

Nominal geometry and force measures for solids and fluids
International Journal of Mechanical System Dynamics, Volume 2, Issue 3, Page 249-252, September 2022., 2022 Abstract Understanding solid‐ and fluid‐inertia forces and their coupling with the gravity potential in complex motion scenarios is necessary for evaluating system stability and identifying root causes of system failure and accidents. Because solids and fluids have an infinite number of degrees of freedom and distributed inertia and elasticity, having ...
