Implementation of an extension to the standard simulation process in OpenSim and validation of simulated user loads

When working with power tools, users sometimes experience high forces that can lead to health problems. There are many different approaches for designing products more ergonomically. In particular, computer simulations are becoming increasingly important. Compared to conventional methods, musculoskeletal human models can be used to investigate, e.g., joint forces and muscle activation with reduced effort. For simulating an application, the kinematic motion and external forces that are acting on the user during working are applied to the model. The subsequent analysis enables an evaluation and comparsion of user loads.
