The no-load drag torque is a crucial factor in the design phase to estimate the power
required by the electric motor in electro-mechanical actuators (EMA). This paper focuses on …

Building a high-fidelity model to identify a connection between a measurable signal variation
and the onset and growth of a fault, which can then evolve in a failure, is a method to …

Ball screws are used to replace traditional sliding screws when high positioning precision
and high performances are requested. In order to preserve their characteristics and extend …

To evaluate the accuracy reliability of machine tools, an evaluation method of accuracy
reliability considering the machining error out of tolerance is proposed, and an accurate …

The ball screws are the machine component most frequently used for transforming rotational
into linear motion of a feed drive, to position the machine tool components carrying the …

The paper proposes an architecture to develop a dynamic flight simulator based on a three
dof parallel platform. The solution is proposed in order to make it possible to assemble an …

Over the past years, a trend toward “more electric” equipment has arisen including flight
control systems, leading to a tendency to replace the electro-hydraulic actuators (EHSAs) …

Born from environmental and cost saving concerns, the recent trend toward “more electric”
aircraft has touched most of the more important on-board systems and equipment. For flight …

The paper introduces a high concentration photovoltaic system developed at Politecnico di
Torino. The system includes a new kind of solar tracker, based on a parallel kinematic …

Aircraft primary flight control surfaces are typically driven by two linear hydraulic actuators
accepting the controlled flows from two independent hydraulic systems. When the actuators …
