Elastic deformation mechanism

WebMay 2, 2024 · Abstract. Flexible manipulators are longer and lighter, which allows them to undergo elastic deformation and vibration. It affects the working accuracy and flexibility of the robot. To enhance the flexibility and flexibility of robot positioning, accurate dynamics modeling and analysis are essential. Therefore, using the space deformation spinor … Before work hardening, the lattice of the material exhibits a regular, nearly defect-free pattern (almost no dislocations). The defect-free lattice can be created or restored at any time by annealing. As the material is work hardened it becomes increasingly saturated with new dislocations, and more dislocations are prevented from nucleating (a resistance to dislocation-formation develops)…
