  • When man invented the wheel, he very quickly learned that if it wasn’t completely round and if it didn’t rotate evenly about it’s central axis, then he had a problem! The wheel would vibrate, causing damage to itself and it’s support mechanism and in severe cases, be unusable. As the task of manufacturing a replacement was so huge and time consuming, a method had to be found to minimize the problem. Research showed that the wheel and its shaft had to be in a state of balance, i.e.

  • In this paper we prove the global existence and uniqueness (regularity) of strong solutions to the three-dimensional viscous primitive equations, which model large scale ocean and atmosphere dynamics. 1. Introduction Large scale dynamics of oceans and atmosphere is governed by the primitive equations which are derived from the Navier-Stokes equations, with rotation, coupled to thermodynamics and salinity diffusion-transport equations, which account for the buoyancy forces and stratification effects under the Boussinesq approximation. ...

  • The last decades have marked the beginning of a new era in Celestial Mechanics. The challenges came from several different directions. The stability theory of nearly–integrable systems (a class of problems which includes many models of Celestial Mechanics) profited from the breakthrough represented by the Kolmogorov– Arnold–Moser theory, which also provides tools for determining explicitly the parameter values allowing for stability.

  • A centrifugal pump is a rotating machine in which flow and pressure are generated dynamically. The inlet is not walled off from the outlet as is the case with positive dis- placement pumps,whether they are reciprocating or rotary in configuration. Rather, a cen- trifugal pump delivers useful energy to the fluid or “pumpage” largely through velocity changes that occur as this fluid flows through the impeller and the associated fixed pas- sageways of the pump; that is, it is a “rotodynamic” pump.

  • The article deals with a research on the design and manufacturing of a dynamic balancing machine, using dynamic load sensors and optical one, for calculating the unbalanced mass in thick rotating part on two choosen correction planes. Dynamic load sensors attached to the bearing supports of the machine help us determine the reaction forces generated by the unbalanced mass of the rotor. These load signals are filtered and digitized at a sampling rate which is synchronous to the rotor via an optical sensors.

  • Multibody simulation consists of analyzing the dynamic behavior of a system of interconnected bodies comprised of flexible and/or rigid components. The bodies may be constrained with respect to each other via a kinematically admissible set of constraints modeled as joints. These systems can represent an automobile, a space structure with antenna deployment capabilities, an aircraft as an assemblage of rigid and flexible parts, a robot with manipulator arms, and so on. In all such cases, the components may undergo large rotation, large displacement, and finite strain effects....

Dynamic seals, however, are used where rotating or reciprocating motion is intended to occur.
