A Study of Vibration Damping Control for Hollow Drive Shaft

Field Programmable Gate Array Implementation of Active Control Laws for Multi-mode Vibration Damping

This paper investigate the possibility and effectiveness of multi-mode vibration control of a plate through real-time FPGA (Field Programmable Gate Array) implementation. This type of embedded system offers true parallel and high throughput computation abilities. The control object is an aluminum panel, clamped to a Perspex box’s upper side. Two types of control laws are studied. The first belo...

Elastoplastic torsion of hollow FGM circular shaft

In many cases, a torsional shaft may be a thick-walled radially inhomogeneous cylindrical object. The hollow shafts made of functionally graded materials (FGMs) are such kind of compositions which were studied in this paper. Cylindrical FG shafts are composed of ceramic and metallic parts with power function distribution across the radial direction. The ceramic phase is isotropic elastic and th...

Robot Vibration Control Using Inertial Damping Forces

High Damping Capacity Coatings for Surface Vibration Control

The damping capacity Q-'of a number of Fe-16%Cr alloys containing (0 6)%A1 and (0 4)%Mo has been investigated and compared to that of thermally sprayed coatings. The magnetomechanical hysteresis loss was determined using a cantilever method and based on the modal analysis technique of flat beam samples. Heat treatments usually enhanced the loss capability, but further annealing destroyed it dra...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
