This work demonstrates with numerical simulations, the feasibility of a wide frequency range and high pressure level piezoresistive microphone based on MEMS technology. An accurate lumped-element model was used to optimize the microphone dynamic response. Mechanical lumped parameters were extracted from structural finite element method (FEM) simulations, while squeeze film fluid parameters were...
As the life age of the existing structures are required to meet the changing demands on civil infrastructures. So strengthening and retrofitting are required. Recently many techniques to strengthen the reinforced concrete beams in flexural by using fiber reinforced polymer (FRP) had appeared. The most famous technique among them is strengthening the (RC) beams with externally bonded FRP sheet t...
This paper presents a methodology to analyze dynamics of flexible space robot using bond graph. In case of space robots the position and orientation of the satellite main body may change when the manipulator moves. Motion of the space robots also induces vibrating motions in structurally flexible manipulators. Researchers working on terrestrial flexible robot arms principally have focused on is...
Abstract In vibratory systems, linear and nonlinear vibration absorbers can be used to suppress the primary and super-harmonic resonance responses. In this paper, the behavior of a nonlinear system with a nonlinear absorber, under the primary and super-harmonic resonances is investigated. The stiffnesses of the main system and the absorber are cubically nonlinear and the dampers are linear. M...
We demonstrate both theoretically and experimentally nonparaxial Mathieu and Weber accelerating beams, generalizing the concept of previously found accelerating beams. We show that such beams bend into large angles along circular, elliptical, or parabolic trajectories but still retain nondiffracting and self-healing capabilities. The circular nonparaxial accelerating beams can be considered as ...
