Vibrations of the Rigid Solid with a Point Constrained to Move on a Mobile Curve
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2015, Vol 12, Issue 1
Abstract
This paper makes a numerical study for the vibrations of a physical pendulum for which the suspension point is constrained to move on a mobile curve. The matrix equation of motion is presented and the study is performed analyzing the variations of different parameters of motion as function of the parameters that define the mobile curve.

Dynamic Design of the Foundation of Reciprocating Machines for Offshore Installations in Persian Gulf
The installation of large and heavy reciprocating machines on offshore constructions demands specific requirements in the design of the foundation with respect to vibrations. Because the use of those piston engines impli...
Evaluation of Optimum Modes and Conditions of Ultrasonic Cavitation Influence on High-Viscous and Non-Newtonian Liquid Mediums
The article is devoted to the results of modeling of the formation of cavitation area under ultrasonic influence on liquid media, which differ in flow curves and acoustic properties. Taking into account influence of liqu...
Parameters Influencing the Focalization Produced by a Graded Phononic Crystal
The geometrical distribution of immersed tubes has considerable influence on the propagation of an incident plane acoustic wave. A periodic distribution represents a phononic crystal (PC), which can be perfectly transpar...
