Abstract: This paper introduces models for electrorheological (ER) structures based on visco-elasticity and sandwich beam theory. The partial differential equations describing the dynamics of an ER sandwich ...

Abstract: This research focuses on real-time position control for draping fabric sliding on a high friction surface. Although fabrics are usually positioned on smooth surfaces with fixed fabric guides to ...

Abstract: An axial force stabilizes the transverse vibration of a beam with pinned and/or clamped boundary conditions. The nonlinearly coupled, longitudinal and transverse equations of motion of the beam ...

Abstract: Parametric excitation is used to control the vibration of a conservative mechanical system. The excitation is varied according to a quadratic, state feedback, control law. If the system has ...

Abstract: This paper investigates the nonlinear dynamic response of a linearly elastic string fixed at one boundary and undergoing constant speed circular motion at the other boundary. The response divides ...

Abstract: One position sensor, a bilinear observer, and quadratic, observer-based feedback to a parametric actuator asymptotically stabilize n-modes of a flexible system. Using a perturbation approach, the ...

Abstract: The minimum damping for asymptotic stability is predicted for Hill’s equation with any bounded parametric excitation. It is shown that the response of Hill’s equation with bounded parametric ...

Abstract: During the manufacture and transport of textile products, yarns are rotated at high speed. The surface of revolution generated by the rotating yarn is called a balloon. The dynamic response ...

Abstract: In this paper, the displacement of an axially moving string is regulated using a control force and a control torque applied to the string via a mechanical guide. Given the hybrid model of ...
