Abstract: This paper describes a method for limiting vibration in flexible systems that have more than one characteristic frequency and mode. It is only necessary to have knowledge of the component mode ...

Abstract: A method is presented to minimize residual vibration of structures or lightly damped servomechanisms. The method, referred to as the proportional plus multiple delay (PPMD) control, involves the ...

Abstract: Tribological studies on 12.7 mm dia steel bearing ball specimens of different composition have been carried out in a “4-ball machine” using certain potentially active heterocyclic compounds-paraffin ...
