A novel, Fourier series based method of control optimization and its application to a discontinuous capsule drive model

Sandra Zarychta et al.

Summary: This paper presents a novel numerical method based on Fourier series for optimizing open-loop control. The method is flexible and can be applied to a wide range of systems, including discontinuous or black box systems with unknown equations. The paper provides the mathematical background, algorithm details, and a practical example to demonstrate the effectiveness of the proposed method. It is expected to facilitate research in the control of non-smooth, discontinuous, or black box systems.

Speed optimisation and reliability analysis of a self-propelled capsule robot moving in an uncertain frictional environment

Maolin Liao et al.

Summary: The dynamics of a self-propelled capsule robot for small-bowel endoscopy driven by internal vibro-impact excitation are studied. An optimization method combining Six Sigma and Multi-Island Genetic algorithms is used to maintain the robot's desired velocity in the uncertain frictional environment of the small bowel. Numerical studies and experimental verification show that the proposed method is effective in optimizing the robot's different motions.

Feature-based intelligent models for optimisation of percussive drilling

Kenneth Omokhagbo Afebu et al.

Summary: The vibro-impact drilling (VID) system, as a rotary-percussion system, utilizes high frequency periodic impacts induced by resonance to cut through rock layers while rotating the drill-string. The system experiences multi-stability due to the inhomogeneous nature of the rock layers, generating different impact motions. This study adopts feature-based classification algorithms to categorize the impact motions and optimize the system's performance.

A pipeline inspection robot for navigating tubular environments in the sub-centimeter scale

Chao Tang et al.

Summary: We proposed a smart material-driven pipeline inspection robot that could fit into sub-centimeter-sized pipes with different curvatures. The robot utilized high-power density elastomer actuators as artificial muscles and efficient anchoring units for transmission. By analyzing the dynamic characteristics and considering soft material properties, the robot achieved rapid motions in varying pipeline geometries. The robot successfully completed inspection tasks in different pipe materials and filled media.

The effect of the presence of obstacles on the dynamic response of single-degree-of-freedom systems: Study of the scenarios aimed at vibration control

Giulia Stefani et al.

Summary: In this paper, the impact of deformable and dissipative obstacles on the nonlinear dynamic response of a system is investigated. The study reveals that the presence of obstacles can have beneficial effects if the proper parameters are selected. Furthermore, a relationship between the stiffness and damping of the obstacles is identified to minimize the maximum mass acceleration.

Post-grazing dynamics of a vibro-impacting energy generator

Larissa Serdukova et al.

Summary: The motion of a forced vibro-impacting incline energy harvester is investigated in parameter regimes with asymmetry in the number of impacts on the bottom and top. Semi-analytical expressions for asymmetric periodic motion with a ratio of 2:1 for impacts on the device bottom and top are obtained, derived through nonlinear maps and impact conditions. Bifurcation diagrams and linear stability analysis validate the numerical solutions for asymmetric motions with different incline angles.

The effect of friction on the vibro-impact locomotion system: modeling and dynamic response

Khac-Tuan Nguyen et al.

Summary: This study investigates the impact of various friction levels on the dynamic response of a vibro-impact locomotion system. Experimental results show that friction not only affects the speed of the system, but also its direction of movement. Bifurcation analysis reveals that different friction levels can lead to different motion states in the system.

Influence of the gap size on the response of a single-degree-of-freedom vibro-impact system with two-sided constraints: Experimental tests and numerical modeling

Giulia Stefani et al.

Summary: This paper investigates the influence of gap amplitude on the experimental response of a single-degree-of-freedom oscillator constrained by two unilateral deformable and dissipative bumpers. The study highlights the effect of transitioning from positive to small negative gaps and the impact of excessive negative gaps on system response. Additionally, secondary resonances in the low frequency range were observed for small positive gaps, and experimental results were accurately reproduced using a numerical model based on identified parameters.
