Applied Mechanics / FEA

Laboratory for Applied Mechanics / Finite Element Analysis (FEA)

Applied Mechanics and its follow-up subjects (i.e. Finite Elements, Machine Dynamics and Dynamics of Multi-body Systems) form an important part in Mechanical Engineering and Mechatronics. The currently available computer-aided design tools are indispensible for problem solving. The Laboratory for Applied Mechanics / FEA provides a modern learning and development environment, in which students learn to use simulation programs efficiently.

Automation Technology and Robotics

Laboratory for Automation Technology and Robotics

Automation is a highly interdisciplinary field in which essential topics of mechanical engineering, mechatronics and electrical engineering are overlapping. It goes along with the fascination to build machines that are able to run processes autonomously.

The lab is focussed on automated assembly. It is equipped with:

  • Transfer systems
  • Assembly robots
  • Programmable logic controllers
  • Pneumatic, electrical and servopneumatic handling systems
  • Various sensors and actuators
  • A wide range of information and communication technology

The main components of automation technology are introduced in practical trainings. Parts of the assembly line have been developed in student projects.

Robotics is a major part of automation. A typical assembly robot (SCARA) and a universal robot as common representatives of the robotics industry are here at disposal. Both are equipped with image processing systems. Besides programming the robots directly at the line, simulation is another essential aspect of the practical training program.

Recently, the automation technology and robotics laboratory was supplemented by a range of mobile, autonomous systems. Wheeled platforms (TurtleBot, NXT and in-house developments) belong to them as well as humanoid robots (Nao), which give an insight into the complex kinematics and programming of humanoid service robots. These robots are able to play soccer as well ...

Practical trainings

The CAD lab is used for the following practical trainings:

  • Basics of CAD
  • CAD/CAM

The participation in Basics of CAD is compulsory for all students. Here they learn the basic 3D techniques required for using a CAD system. The training is performed in groups with 15 person.

The CAD/CAM practical training comprises two parts: In the first part (CAD), the capabilities of modern CAD systems are demonstrated. Students are introduced to ways of modeling and assembly modeling and much more by using the Inventor CAD system.

In the second part of the training (CAM), students deal with the computer-aided generation of milling programs. This part of the training takes place in the CAD/CAM lab.

The lab holds approximately 15 experimental setups (in different versions, each 2-6 times), allowing students to conduct measurements in Mechanics, Electrodynamics, Optics and Solid State Physics. In addition, the following devices are available for scientific studies: two photospectrometers, a Faraday spectrometer, a setup for measuring optical modes in planar magneto-optical waveguides, an ellipsometer and optical benches with various optical components.

            A particular highlight of the Physics Laboratory is the large collection of physical gadgets (toys) which can be used for a variety of creative experiments.

            Laboratory for Production-related Measurement Techniques

            This laboratory is used for experiments that belong to the practical training of the course Manufacturing Processes (course No. 82106).

            The accuracy of components that are being produced plays an ever-increasing role in manufacturing technology. Therefore, the geometric dimensions of the components as well as their surface quality have to be checked and compared with the given requirements already during the production process.

            Furthermore, students are free to use the laboratory for projects or their bachelor and master theses.

             

            Equipment

            • Surface reference standards
            • Vernier caliper
            • Outside micrometers
            • Gauges and light section microscope
            • Mahr form tester to detect surface deviations (circularity), eccentricity deviations, and deviations from plane-parallelism
            • Various measuring instruments to determine such surface characteristics as roughness depth, smoothing depth, mean roughness value, and load-bearing behaviour

              The instruments can be used for measurements in the workshop (MarSurf PS1 without any further documentation) as well as for measurements in the test laboratory (MarSurf M300 + RD18 with wireless data transmission to the evaluation computer).

            GoetheLab for Additive Manufacturing

            GoetheLab for Additive Manufacturing

            The laboratory is used for the courses Rapid Prototyping and Laser Technology, but also for the Faculty of Mechanical Engineering and Mechatronics' master degree programs. Go to the GoetheLab homepage.

            Prof. Gebhardt (faculty 8), who leads the teaching and research field "High performance processes in manufacturing and rapid prototyping", has worked mainly in the area of additive manufacturing of plastic prototypes. His findings have drawn international attention.

            At the end of 2010, he included metal processing in his studies on additive prototype manufacturing. Thus he entered not only uncharted territory for the FH Aachen University of Applied Sciences, but also tackled a new issue that industrial manufacturers were facing. In the meantime, the findings of different research projects have paved the way that allows to process various steel alloys as well as precious metals, e.g. silver.

            The cooperation with the company CP-GmbH and its extensive practical experiences led to the following (meanwhile regarded as standard) textbook:

            • Gebhardt, A.: Generative Fertigungsverfahren. Rapid Prototyping – Rapid Tooling – Rapid Manufacturing.
              Fachbuch, 499 Seiten, 3. Auflage, Carl Hanser Verlag, München / Wien, 2007

            as well as to the concise study edition in English language:

              Thermodynamics and Energy Technology

              Laboratory for Thermodynamics and Energy Technology

              Thermodynamics is a basic course that belongs to the curriculum's required subjects. At present, the practical training in Thermodynamics consists of the following three experiments:

              • Temperature measurement procedures
              • Vapor-liquid phase equilibrium (measuring the vapor pressure curve of carbon dioxide)
              • Processes in humid air

              The experiments are designed such that students can conduct them on their own.

              Energy Technology is an elective course for which the lab provides experimenal set-ups and testing equipment for the following issues:

              • Thermal heat pumps
              • Combined heat and power units
              • Heat exchanger
              • Thermography

               

              Equipment

              • General lab measurement instrumentation to measure electric variables
              • Testing equipment for the Temperature Measurement practical training
              • Testing equipment to measure the vapour pressure curve of carbon dioxide
              • Experiamental set-up Humid Air
              • Heat pump
              • Several thermographic systems
              • Gas-powered combined heat and power unit
              • Steam-powered combined heat and power unit
              • Experiamental set-up heat transfer test rig (under construction)
              • Experiamental set-up shell-and-tube heat exchanger
