Purpose The paper aims to reduce the low-frequency resonance and residual vibration of robot during operation, improve working accuracy efficiency. A reduced weight large load-to-weight ratio can practical application a collaborative robot. However, flexibility caused by leads operation robot, which reduces vibrations are suppressed using modified trajectory-planning method. Design/methodology/approach rigid-flexible coupling dynamics model is established finite element Lagrange methods,...
The investigation of the mechanical properties rock mass can be effectively carried out through rock-like material experiments. In this study, polystyrene foam particles were utilized as a novel for simulating initial damage within rocks. Our research involved development sandstone-like materials with comparable to actual sandstone. These then subjected orthogonal tests, allowing us identify key factors that have substantial impact on parameters influencing considered in tests proportion...
Aiming at the problem that vibration of space robot will reduce dynamic accuracy robot, a method suppression through trajectory planning is proposed. First, joint was simplified to linear torsion spring, and flexible rod modelled using finite element method, resulting in motion model robot. Then, rigid-soft coupled combined with Lagrange established. Using model, factors influencing behaviour robots were analysed. Finally, subjected planning. As verified by experimental analysis, different...
