Technical Mechanics for Electrical Engineering (MW2286)

Technical mechanics is a fundamental discipline in engineering sciences. The goal is to describe the deformation and motion of bodies caused by forces. The range of subjects in this course covers statics and the computation of reactions in planar structures, kinetics and the description of rigid body motions. Newton's and Euler's laws and advanced dynamic methods are used to describe the behavior of multi-body systems. Finally the fundamentals of elastostatics are covered and simple planar problems like calculating the bending in Bernoulli beams is demonstrated.

Dynamics of Mechanical Systems (MW1421)

In modern systems structural components move and vibrate in a complex environment where coupling with forces arising from, for instance, acoustics, electrostatics, thermal effects or magnetics play an important role. We will therefore, in this course, shortly explain the key basics of dynamics and build on this the influence of such multiphysical interaction on the dynamical behavior of mechanical system. Such topics are certainly of interest not only for students from mechanical engineering, but also for electrical or civil engineers for instance.

 

Robot Dynamics (MW0867)

In this course, students learn to describe the kinematics of rigid tree-structured robots and to model their dynamics. Building on this, basic methods for trajectory planning and optimization are introduced. Finally, typical control concepts for different tasks are presented. The theoretical basics are each illustrated by simple examples.

 

 

Applied Biorobotics (MW2388)

This course is using the example of a bipedal walking robot to teach biorobotics concepts. Additionally the training of important soft skills (communication, literature research, presentation, feedback, use of different media) will be encouraged. Students learn how to tackle complex problems from a variety of possible angles, explore solutions and develop them in a group environment. Students will document their learning progress in 10 assignment submissions throughout the lecture period.

At the end of this course students are able

  • to explain concepts for using biological insights for solving technical problems and apply them to specific problems
  • to describe the role of models for the knowledge transfer from biology into robotics, to characterize their specific limitations and to apply them to technical problems
  • to differentiate advantages and disadvantages of bio-inspired optimization algorithms and to apply them to optimize their solutions
  • to apply the acquired knowledge to a practical experiment and design a controller for a legged robot

Multibody Simulation (MW0866)

Multibody systems are technical systems consisting of different rigid or flexible bodies. The connections may be modeled with classical force laws or realized by kinematical constraints. In the meantime multibody simulation programs are well established and can be found in a variety of industrial sectors, for example in aeronautical engineering or in the automobile industry. The course focuses on the underlying fundamentals and numerical algorithms of multibody simulation.

 

 

Structural Dynamics (MW2391)

The aim of the lecture is to revise the general theory of vibration in solids and structures, understand the various analysis types (free vibrations, harmonic analysis and time response), and to have a thorough understanding of the important numerical procedures necessary to perform the modelling and simulation of real engineering problems. Special focus is placed on the link between numerical methods and application.

Experimental Vibration Analysis (MW1995)

Every moving machine causes vibrations that might be harmful to itself or its surrounding environment. In this lecture, we provide basic knowledge to experimentally analyze vibrating systems. While we are trying to convey the necessary basic theory, we also try to focus on the application of experimental techniques using practical examples.
The main topics of this lecture are:

  • Modelling of dynamic system in the time and frequency domain.
  • Digital Signal Processing.
  • Experimental Modal Analysis.

We also give two lab tours during the lecture, showing practical examples of test setups.

Lab on Vibration Measurements (MW0300)

This lab seminar enables the application of methods for experimental vibration analysis. The aim is to provide students with tools for identifying and distinguishing typical vibration phenomena on real machines and structures. The lab seminar includes the following experiments:

  • FFT: Analysis of synthetic signals
  • Strain gauges:Measurement with strain gauges
  • Magnetic bearings: dynamic characteristics
  • Beam: Eigenfrequencies and mode shapes
  • Modal analysis: Modal parameter of an academic structure

 

 

Engineering Mechanics - Vibrations (Practical) (MW0285)

In this course, the different mechanisms of the origin of mechanical vibrations are to be worked out in the context of a practical course. The aim is to build a bridge between theory and practice. The practical course includes the following experiments:

  • MoI: moment of inertia through torsion pendulum
  • Balancing bar: rigid rotor, balancing machine
  • Parametric pendulum: parametric excitation, stability
  • Balancing bar: upright pendulum, stabilization with controller
  • Friction pendulum: self-excitation, phase curve
