OVERVIEW

Fluid Power Automation studies power transmissions that operate in the presence of compressed air or pressurized oil, controlled by micro-processor electronic units.

The course aims to provide on one hand the tools for the knowledge, identification and analysis of pneumatic and oleohydraulic components and systems, and on the other, elements of in-depth analysis on their use in industrial automation systems, through a theoretical and experimental approaches.

 

AIMS AND CONTENT

LEARNING OUTCOMES

Pneumatic and hydraulic components and systems for actuation, command and control. On-off, proportional and servo-assisted units. Interfacing with PLC and dedicated control units, centralized and distributed. Integrated and hybrid components. Hydraulic applications for primary actuations and on-board auxiliaries.

AIMS AND LEARNING OUTCOMES

The purpose of the Fluid Power Automation teaching is to provide an in-depth analysis of the drives operating in the presence of air or oil under pressure, for power implementations in the naval and industrial sectors in general.

At the end of the course the student will have acquired theoretical knowledge on fluid drives and practical skills in the creation of command circuits. thanks to the labotatory activities.

Specifically, the student will be able to:

  •      know the operating characteristics of the main hydraulic and pneumatic components
  •      select components according to the operating specifications
  •      analyze drive circuits
  •      examine integrated solutions between fluid power units and microprocessor control units

PREREQUISITES

To effectively address the teaching content, the following basic knowledge is required:

  •      elements of hydrodynamics
  •      elements of mechanics of machinery
  •      industrial design elements

TEACHING METHODS

The course includes, in addition to lectures and exercises in the classroom, as well as the development of substantial laboratory activities. There are approximately 40 hours of frontal lessons and 20 hours of laboratory hours. Laboratory activities are carried out by the teaching professor. In the laboratory the students are divided into groups and operate directly in the implementation of drive circuits and in their dynamic simulation.

SYLLABUS/CONTENT

The course program includes the presentation and discussion of the following topics:

Pneumatics: air  treatment and distribution. Compressors. Actuators. Pneumatic and electro-pneumatic valves, on/off and proportional. Circuit  components  and selection criteria. Pneumatic circuits for automation. Dynamic models. Special pneumatic components. Hydraulics: characteristics and fluid treatment. Pumps and motors. Commands and controls on / off, proportional and servo- assisted. Criteria for the selection of components. Hydraulic circuits for automation. Dynamic models. Hydrostatic transmissions for automation. CAD / CAE for fluid systems: modeling of circuits, simulation, computerized catalogs. Sensors and transducers for automatic fluid circuits. Integrated sensors. Interfacing with microprocessor control units: hardware and software architectures. Flexible automation in fluidic systems  via programmable logic controllers ( PLC),dedicated electronic units, industrial PCs. Distributed control systems : fieldbus , ASI . Specific aspects of pneumotronics and oleotronics . Innovative and "smart" components. Drives dedicated to specific applications: steering, anti-roll stabilizer fins, trim blades controllable pitch propellers.

Many of the issues analyzed theoretically will find practical feedback in laboratory activities.

EXAMS

EXAM DESCRIPTION

The exam includes an oral test. Here,Three questions will be formulated to the student concerning the topics dealt with in teaching, one of which is oriented to the themes developed during the laboratory exercises.

ASSESSMENT METHODS

The question asked about the topics developed in the laboratory tends to ascertain the student's ability to summarize the practical tests carried out and to correlate them with the general problems analyzed in the course. The other two questions tend to ascertain the mastery over the subjects dealt with, with particular reference to the knowledge of the operating principles of components and fluid sub-systems and the selection procedures of components based on the operating specifications.
