Goals

The aim of this module is to give the students skills to analyze, design and simulate devices using fluids: hydrostatic and hydrodynamic bearings, hydraulic systems : fluid power control.
The application areas are very diverse in industry, aerospace, automotive ...
The emphasis is on learning through project, two case studies conducted by outside contributors and an introduction to the dynamic simulation of hydraulic circuits using AMESim©.
A Practical Work on an electrohydraulic position control is proposed. The objective is to analyze the structure, identifying characteristics, to provide a control setting, performing tests of response to typical inputs, to finally build a AMESim model and compare measures and results simulation.

Content

Fluid power control:

Hydraulic generations,
Controls on variable-displacement pumps : constant horse power control, pressure and combined flow/pressure (load sensing) compensator,
Hydrostatic transmissions (closed circuit),
Servo and proportionnal valves (technologies, static and dynamic characteristics),
Hydraulic Actuators: motors and hydraulic cylinders (technologies, static and dynamic characteristics),
Hydraulic and electro-hydraulic servomechanisms.

Prerequisites

Core Curriculum General Mechanics, and Fluid Mechanics.
