Multibody dynamics is the main research area of Prof. Seifried’s group. Multibody dynamics is a sub-field of Mechanics and deals with mechanical and mechatronical systems undergoing large nonlinear working motion. The group works on methods for modelling, simulation, optimization and control of rigid and flexible multibody systems. The experimental validation and the transfer of the methods to industrial application are core part of our group’s research. Typical application fields are lightweight robotics, vehicle- and machine dynamics, automation technology, wind power, energy harvesting and biomechanics. Besides multibody dynamics, traditionally the institute works also on ocean engineering. Here the focus is on mechatronic systems in ocean engineering. The group is part of the initiative Machine Learning in Engineering at TUHH.
