In the joint project DYMARA we are developing an innovative digital manikin with detailed modeling of skeletal muscles and fast numerical algorithms.
With this manikin it should be possible to integrate humans into their working environment in an optimal way and to avoid fatigue, illnesses and accidents at the workplace. In addition to these ergonomic aspects, the human model is also used for therapy planning in the muscular area and for the design of prostheses and orthoses.
In order to capture the dynamics of the musculoskeletal system with sufficient accuracy, we follow a modelling approach based on the method of mechanical multi-body systems (MBS). Such models are inspired by robotics and are already used in many biomechanical applications. However, the modelling of the musculature still poses a great challenge, in particular the computing time and the consideration of anatomical and physiological conditions pose challenges.
