Abstract: In this paper, we formulate and explore the characteristics of iterative learning in ballistic control problems, where the projectile experiences a constant gravitational force and a fluid drag force that is quadratic in ...

Abstract: Vibrationdriven systems can move progressively in resistive media owing to periodic motions of internal masses. In consideration of the external dry friction forces, the system is piecewise smooth and has been shown to ...

Abstract: This paper utilizes an effective control strategy to suppress the regenerative chatter in a plungegrinding process. To begin with, the dynamical interaction between the workpiece and the grinding wheel is considered as a ...

Abstract: This paper presents a new type of flexible screw mechanism (FSM), which is composed of a nut, flexible axle, and roller. It can be used in a worm robot to achieve flexible peristaltic motion, as well as curvilinear motion ...

Abstract: In this paper, time-delayed feedback (TD-FB) control is introduced for a nonlinear vibration isolator (NL-VI), and the isolation effectiveness features are investigated theoretically and experimentally. In the feedback ...

Abstract: Zirconia ceramics which are sometimes called “ceramic steel” have gained significant interest because of their excellent properties. However, it is desired to maintain the surface quality while increasing the economics of ...

Abstract: An adaptive vibration isolation system is proposed in this paper to combine the advantages of both linear and nonlinear isolators. Because of the proposed structural piecewise characteristics for different levels of response, ...

Abstract: The purpose of this paper is to present a new algorithm for coupling discrete-element and finite-difference methods for three-dimensional problems. The finite-difference method (FDM) and the discrete-element method (DEM) ...

Abstract: A new method for traffic tunnels with large deformations of soft rock is produced based on the research and development of a new yielding anchor and on the successful application of a large deformation tunnel to a coal ...
