Analysis of the kinematic chain for the motion transmission from the tractor to a rotary harrow

The present article illustrates the study of the kinematic chain between tractor and rotary harrow used for the motion transmission from the PTO to the tool. The study has focused also on the…

Much higher performances than with conventional air supports

Active air bearings controlled by piezoelectric actuators

Federico Colombo, Luigi Lentini, Terenziano Raparelli, Vladimir Viktorov, Politecnico di Torino –  The article illustrates some of the most recent typologies of active air bearings, controlled by piezoelectric actuators. This active control methodology is…

A pneumatic control system increases the stiffness of pneumostatic bearings

Control of an air bearing through diaphragm valve

This article presents the experimentation of a pneumatic control system to increase the stiffness of pneumostatic bearings. Air bearings in general, and pneumatic ones in particular, allow precision motions since almost frictionless and…

A good management matters

Guido Belforte –  Pneumatics or electro-mechanics? Very often, we hear this question asked by engineers who must choose the most suitable components for satisfying the requirements of a new system. The answer is…

A turbocompressor to feed a fuel cell system for vehicle applications, needing compactness and lightness.

Development of a compressor in mobile applications

Federico Colombo, Terenziano Raparelli Politecnico di Torino –  In the ambit of the CARI regional project, the Politecnico di Torino is developing a turbocompressor to feed a fuel cell system for vehicle applications,…
