The paper investigates a nonlinear vibration mitigation strategy of variable length pendulum subjected to harmonic external excitation. A absorber in form tri-pendulum system is used reduce the response primary pendulum. Thus, non-stationary problem using another passive absorber. Due genuine interest capturing dynamic interaction, numerically studies performance mass and absorber, first, by co...

Abstract In order to study the influence of structural factors launch device on missile tilt projectile dynamics, a dynamic model platform was established based finite element method. The effects shock absorber stiffness, angle between and horizontal plane were studied platform’s ejection response characteristics. research results show that greater rigidity absorber, smaller plane, vibration am...

To address the contradiction between ride comfort and handling stability, a new vibration-absorbing wheel structure with time-delay feedback control was proposed by applying feedback-controlled dynamic vibration absorber to structure. Using H2 optimization particle swarm algorithm (PSO), design parameters of were obtained sprung mass acceleration (SMA), suspension deflection (SD) tire (DTD) as ...
