Analytical, numerical solutions and study of stability, resonance for nonlinear vibro-impact system under different excitation
Because of the existence of impacts, the vibro-impact system is discontinuous and strongly nonlinear, such as hammer-like devices, rotor-casing dynamical systems, heat exchangers, fuel elements of nuclear reactor, gears, piping systems, wheel–rail interaction of high speed railway coaches. Researches into the dynamic behavior of vibro-impact systems have important significance in optimization d...
متن کاملThe Transient Dynamics of a Beam Mounted on Spring Supports and Equipped with the Nonlinear Energy Sink
The transient dynamics of a beam mounted on springer-damper support and equipped with a nonlinear energy sink (NES) is investigated under the effects of shock loads. The equations of motion are derived using the Hamilton’s principle leading to four hybrid ordinary and partial differential equations and descritized using the Galerkin method. An adaptive Newmark method is employed for accurate an...
متن کاملVibration Analysis of a Nonlinear System with a Nonlinear Absorber under the Primary and Super-harmonic Resonances (TECHNICAL NOTE)
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...
متن کاملPhysical Nonlinear Analysis of a Beam Under Moving Harmonic Load
A prismatic beam made of a behaviorally nonlinear material is analyzed under aharmonic load moving with a known velocity. The vibration equation of motion is derived usingHamilton principle and Euler-Lagrange Equation. The amplitude of vibration, circular frequency,bending moment, stress and deflection of the beam can be calculated by the presented solution.Considering the response of the beam,...
