The phrase "active bearing" is correct and usable in written English.
It can be used in contexts related to navigation, engineering, or psychology, where it refers to a person's posture or the direction of a moving object.
Example: "The pilot maintained an active bearing on the aircraft's trajectory to ensure a safe landing."
Alternatives: "dynamic posture" or "engaged stance."
This paper presents an active bearing for reducing the radiated structure borne noise of rotating machinery.
This paper offers a detailed description of a laboratory installation furnished with the active bearing and the conducted experimental investigation.
The control action of this active bearing is selected based on two different strategies: a simple proportional integral derivative controller and an optimal controller.
The obtained results prove the viability of the proposed active bearing design, validate the available simulation tool and exemplify on a conceptual level the operational benefits from introducing this technology into standard LEG Tilting Pad Bearings.
The developed model is then used to simulate a simple system, in order to portray the feasibility of affecting its static and dynamic properties by introducing this novel active bearing design.
In active bearing applications, on the other hand, the dynamic bearing force, induced by actuation of the gap geometry or supply pressure, provides for a means of enhancing bearing static and dynamic performance, when integrated in a mechatronics system context.
Many researchers have explored the use of active bearings, such as non-contact Active Magnetic Bearings (AMB), to control imbalance vibration in rotor systems.
Active bearings allow the use of specialized control algorithms which eliminate the bearing forces caused by unbalances.
Using this superconducting axial bearing and the active bearings for the rotor radial positioning, a fully levitating vertical-shaft inductive machine has been tested.
Two observer types accounting for this problem, a disturbance observer and an unknown input observer are applied to a rotor system with piezoelectric active bearings.
It is shown that active bearings provide interesting advantages and additional features for substrate positioning, enabling a rather simple and cost effective stage design, suitable for next generation semiconductor applications.
