Group of participants

You are an engineer, practitioner, manager or supplier in the fields of mobile hydraulics, fluid production or in the construction industry.

 

Motivation

Hydraulic systems, such as those found on mobile excavators or stationary presses, are used for high power transmission. Due to the economic importance of hydraulic systems, intensive research is carried out in the entire field of hydraulics, which leads to a continuous optimization of hydraulic systems. The training course is designed to give the technically minded participants a basic understanding of the functioning and design of hydraulic systems. The training is divided into the sections "Basics of hydraulics" and "Design and modelling of hydraulic systems".

The training is manufacturer-independent and considers all possible fields of application of hydraulics.

The "Hydraulics" training course is structured into two parts: "Fundamentals of hydraulics" and "Design and modeling of hydraulic systems".

Part 1: Fundamentals of hydraulics

In the first section, the basics of hydrostatics and hydrodynamics are addressed to the extent that flow equations can be used and flow forces of hydraulic components can be calculated. The mathematical derivation of the physical laws is largely omitted in the course of the training. Since the choice of the pressure fluid plays an ever-increasing role with increasing sensitivity to environmental issues, the structure and properties of biodegradable and flame-retardant fluids are then dealt with in addition to the classic mineral oils. The components for the construction of hydraulic systems such as pumps, valves and cylinders are discussed in detail during the training. The goal is to give a broad overview over the different pump, motor and valve designs. Finally, entire hydraulic networks and their essential controls are presented. Complex circuit diagrams, among other things, are discussed in detail. After the training, the participant is able to understand the function of hydraulic components and more complex hydraulic circuits.

Part 2: Design and modeling of hydraulic systems

The second part of the training continues with the design and modelling of hydraulic systems. In this area, the topics of controlled systems and mobile system architectures are dealt with, adapted to the interests of the participants.

Option 2a: Modelling and control of hydraulic systems

The topic starts with application possibilities of controlled hydraulic systems. The possibilities of controlled systems are explained clearly using practical application examples and challenges in the design of controlled systems are highlighted. Based on this, the common hydraulic components are introduced and the necessary mathematical and physical relationships are taught. Systematic control concepts of hydraulic drives are explained and elaborated in detail using practical examples such as power steering systems or pump controllers.The usual controller concepts, from force, torque and pressure control to speed and position control, are explained in detail. A focus is on the modeling of the individual components in an functional diagram and the subsequent analysis of the resulting transfer functions.

Option 2b: Mobile system architectures

The training part of the mobile architectures starts with the presentation of different mobile machines and their systems. The systems of the mobile work machines are systematically classified according to their characteristics and functionally explained. In the training part steering and driving systems of mobile machines are worked up. The hydraulic power steering systems commonly used in passenger cars and trucks are also explained and then continued with the steering systems of commercial and construction vehicles, which are often based on fully hydrostatic steering. The different concepts of hydraulic power transmission in the drive train of vehicles, ranging from fully hydrostatic traction drive and hydraulic-mechanical power split transmissions to modern hybrid concepts that are able to recuperate energy, will be discussed. A focus of the training section is on hydraulic drive systems for mobile machines.Option 2b: Mobile system architectures

Open-center systems with positive or negative volume flow control, closed-centre systems and load-independent systems are dealt with in detail. The focus here is on enabling the participants to differentiate between the various system types and to be able to evaluate them fundamentally with regard to their system-specific functionality.
