Dynamics of Machines
The Technical Mechanics Group has developed competences in the field of vibration reduction of machines by working on machine-dynamic problems in cooperation with and on behalf of industrial partners. In the focus of the investigations are
|•||the reduction of unbalance excitations|
|•||the insulation of structure-borne sound and|
|•||the vibration-isolating installation of machines.|
A wide range of measuring equipment is available for all the above tasks.
Multibody and Structural Dynamics
The investigation of the dynamic behavior of complex mechanical systems and the dimensioning of structures (supporting structures, beams, plates, etc.) under static, dynamic and thermal load are among the important fields of activity of
|•||the computer-aided simulation of multi-body systems and|
|•||the finite element method|
are used as efficient methods in the field, especially for virtual product development. The fields of application are robotics (locomotion and manipulation) and biologically inspired sensor technology.
Magnetic hybrid materials
The application of magnetic hybrid materials, such as magnetoactive elastomers, enables the realization of actuator systems with complex mechanical behavior that can be adapted to the current operating situation. This is the result of magnetically controllable particle-matrix interactions. In this thematic field, the Technical Mechanics Group focuses on the model-based design of such structures that reduce the control effort. Magnetoactive elastomers offer an adequate approach for the motion and control of systems with “intelligent” mechanics. Apedal (i.e. legless and wheelless) locomotion systems and compliant grippers are current application fields.
Multi-stimulable elastomeric materials
Hybrid elastomer materials with actuator and/or sensor properties enable new approaches to the use of compliant materials in robotics. By multiple stimulation of these materials by temperature and magnetic fields, mechanical properties can be specifically adapted to the task at hand. In this innovative field of research, the Technical mechanics Group realises basic research for the synthesis of hybrid elastomer materials with
|•||soft magnetic particles|
|•||thermoplastic particles and|
|•||thermoplastic elastomer matrix.|
Mobile robots are one of the paradigms of mechatronics because they require a multidisciplinary approach to problems in mechanics, electrical engineering and computer science. Based on the specific competencies in mechanics within the field, research focuses in this area are
|•||the kinematics and dynamics of systems with omnidirectional wheels, including their structural design|
|•||the system analysis, modelling and parameter identification|
|•||the derivation of model-based control and regulation strategies and|
|•||the system integration and prototyping.|
