A Method for Use of Cyclic Symmetry Properties in Analysis of Nonlinear Multiharmonic Vibrations of Bladed Disks
An effective method for analysis of periodic forced response of nonlinear cyclically symmetric structures has been developed. The method allows multiharmonic forced response to be calculated for a whole bladed disk using a periodic sector model without any loss of accuracy in calculations and modeling. A rigorous proof of the validity of the reduction of the whole nonlinear structure to a secto...
متن کاملGranular friction: Triggering large events with small vibrations
Triggering large-scale motion by imposing vibrations to a system can be encountered in many situations, from daily-life shaking of saltcellar to silo unclogging or dynamic earthquakes triggering. In the well-known situation of solid or granular friction, the acceleration of imposed vibrations has often been proposed as the governing parameter for the transition between stick-slip motion and con...
متن کاملFriction Induced Vibrations: Oscillatory Instability with Dissipative and Gyroscopic Influences
Despite all efforts in the past, brake squeal is still a problem. Even detailed simulations only hardly allow for good predictions and the discrepancy to experiments may be considerable from case to case. This paper revisits the general pattern of the equations of motion of moving continua and shows how transport motions provoke gyroscopic terms. Concerning the contact formulation, Lagrange-Mul...
متن کاملSuppression of friction by mechanical vibrations.
Mechanical vibrations are known to affect frictional sliding and the associated stick-slip patterns causing sometimes a drastic reduction of the friction force. This issue is relevant for applications in nanotribology and to understand earthquake triggering by small dynamic perturbations. We study the dynamics of repulsive particles confined between a horizontally driven top plate and a vertica...
متن کاملTactile perception by friction induced vibrations
When a finger moves to scan the surface of an object (haptic sensing), the sliding contact generates vibrations that propagate in the finger skin activating the receptors (mechanoreceptors) located in the skin, allowing the brain to identify objects and perceive information about their properties. The information about the surface of the object is transmitted through vibrations induced by frict...
