Control of networks of Euler-Bernoulli beams [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 1999 In this very important paper the problem of exact controllability of hyperbolic systems of networks of Euler-Bernoulli beams by boundary action is considered. The authors show (Petrovsky systems on one-dimensional networks are considered) how to manage the network structure and the controllability problem using the Hilbert Uniqueness Method (HUM) of ...

Nonlinear Vibration Characteristic Analysis of Electric Vehicle–Road Coupling System
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT In‐wheel motor drive is the developing direction of automobile electrification and intelligence. However, the increased unsprung mass in in‐wheel motor‐driven electric vehicles (IWMEVs) leads to higher dynamic tire loads, thereby intensifying vehicle–road coupling interactions. To address this problem, an 11‐degree‐of‐freedom nonlinear dynamic

Vibration Attenuation of Cantilever Beam Using Electromagnetic Delayed Feedback
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study presents a combined analytical and numerical investigation of a single‐input single‐output delayed feedback controller designed to suppress vibrations in a cantilever beam actuated by an electromagnet positioned beneath its free end. An analytical model was developed using the linearized equation of motion for a transversely excited

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review
Journal of Field Robotics, EarlyView.ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.
