Vibration of Rotating Bladed Disc Excited by Stationary Distributed Forces

Optimum Pareto design of vehicle vibration model excited by non-stationary random road using multi-objective differential evolution algorithm with dynamically adaptable mutation factor

In this paper, a new version of multi-objective differential evolution with dynamically adaptable mutation factor is used for Pareto optimization of a 5-degree of freedom vehicle vibration model excited by non-stationary random road profile. In this way, non-dominated sorting algorithm and crowding distance criterion have been combined to differential evolution with fuzzified mutation in order ...

FGM ROTATING DISC FABRICATE BY Al/Al2O3

Our aim of is to develop a processing method for a rotating disc made of functionally graded materials (FGM), by stacking the slurry, layer by layer in a radial direction. A three-layer functionally graded material of Al/Al2O3 is fabricated with compositions of 10, 20, 30 vol.% Al2O3. The ceramic composition increases from the discs inner (centre) to the outer. The combination of these material...

Experimental Investigation of Mistuned Bladed Disks System Vibration

EXPERIMENTAL INVESTIGATION ONMISTUNEDBLADED DISK SYSTEM VIBRATIONbyJia Li Co-Chairs: Christophe Pierre and Steven L. Ceccio Bladed disks are critical structural components in jet engines and other turbomachin-ery. The nominal design for a bladed disk is typically assumed to have identical blades.However, there are always small, random variations in the blade properties d...

Vibration Analysis of Composite Laminate Plate Excited by Piezoelectric Actuators

Piezoelectric materials can be used as actuators for the active vibration control of smart structural systems. In this work, piezoelectric patches are surface bonded to a composite laminate plate and used as vibration actuators. A static analysis based on the piezoelectricity and elasticity is conducted to evaluate the loads induced by the piezoelectric actuators to the host structure. The load...
