Vibrations in Rotary Machines ScienceDirect

Jan 01, 2014· One of the approaches to simulation of blade vibration in rotating machinery is to use a coupled solver, as shown in Fig. 7.23(a). In this method, solutions of the flow solver and the structural solver are combined through mesh deformations, boundary conditions, and forces, at each time step of the unsteady calculation.

GROUND-BORNE VIBRATIONS DUE TO PILING OPERATIONS

A body of vibration data gathered from press-in sites in Japan and the UK is presented, from which a semi-empirical method for the prediction of the ground-borne vibrations associated with press-in piling is derived. Aided by this work, designers can assess the possibility of specifying the press-in technique in areas sensitive to vibration.

Rotary atomizers Wikipedia

Rotary atomizers work on the principle of centrifugal energy; this energy is used to produce a high relative speed between the fluid and air which is essential for atomization. A rotary atomizer comprises a rotating surface. This surface can be in the form of a flat or a vaned disc, a cup, or a slotted wheel.
