Biomimetics as a Functional Engineering Framework for Mechanical Systems: A PRISMA-Guided Systematic Mapping of Sensing, Inspection, Access Robotics, and Condition Monitoring (2016–2026) [PDF]

open access: yesBiomimetics
Mechanical engineering systems must sense, inspect, and navigate constrained environments and operate adaptively under uncertainty—requirements that map structurally onto capabilities achieved by biological systems through distributed sensing, morphology-

Implementations of Full State Feedback Robust Control Designs for Mechanical Systems Using Only Positions or Velocities Output Feedback

open access: yesIEEE Access, 2022
This paper proposes a new design and practical implementation of a robust ${\mathcal H}_{\infty }$ control applied to some mechanical systems considering in the controller design full access to the state variables and in the equivalent controller ...

Lagrangian mechanics of active systems [PDF]

open access: yesThe European Physical Journal E, 2021
Abstract We present a multi-scale modeling and simulation framework for low-Reynolds number hydrodynamics of shape-changing immersed objects, e.g., biological microswimmers and active surfaces. The key idea is to consider principal shape changes as generalized coordinates and define conjugate generalized hydrodynamic ...

Flat-Panel Mechanical Beam Steerable Array Antennas With In-Plane Rotations: Theory, Design and Low-Cost Implementation

open access: yesIEEE Open Journal of Antennas and Propagation, 2021
We present a compact, flat-panel phased-array antenna design that beam steers using only mechanical in-plane rotations. We explain the steering mechanism and characterize the beam analytically and numerically.

CAD-Based Design Optimization of Four-Bar Mechanisms: An Emergency Ventilator Case Study

open access: yesDesigns, 2023
The design optimization of mechanisms is promising as it results in more energy-efficient machines without compromising performance. However, machine builders do not apply state-of-the-art methods, as these algorithms require case-specific theoretical ...

The Routh theorem for mechanical systems with unknown first integrals [PDF]

open access: yesTheoretical and Applied Mechanics, 2017
In this paper we discuss problems of stability of stationary motions of conservative and dissipative mechanical systems with first integrals. General results are illustrated by the problem of motion of a rotationally symmetric rigid body on a perfectly ...

Displacements of the Levitation Systems in the Vehicle Hyperloop

open access: yesEnergies, 2020
The paper will present a mathematical model for the guideway as a continuous system, followed by a moving force coming from the capsule and the capsule as a discrete system.

Deployment of Solar Sails by Joule Effect: Thermal Analysis and Experimental Results

open access: yesAerospace, 2020
Space vehicles may be propelled by solar sails exploiting the radiation pressure coming from the sun and applied on their surfaces. This work deals with the adoption of Nickel-Titanium Shape Memory Alloy (SMA) elements in the sail deployment mechanism ...

A Mechanical Feedback Classification of Linear Mechanical Control Systems

open access: yesApplied Sciences, 2021
We give a classification of linear nondissipative mechanical control system under mechanical change of coordinates and feedback. First, we consider a controllable case that is somehow a mechanical counterpart of Brunovský classification, then we extend ...
