Hybrid approach to modelling of biomechanical systems

Two main methods of mathematical modelling of biomechanical systems: finite element method (FEM) and method of multi-body system analysis are compared in this paper. Main advantages and limitations of the both methods are pointed out. Then a compromise, task dedicated, "hybrid" solution is proposed. The model is implemented in the MADYMO software environment. The final conclusion is, that in the nearest future the development and utilisation of "dedicated" (designed for specific purposes) models of various accuracy representing individual parts of the human body, where the method of multi-body systems analysis with certain modifications would be used as the primary model, and some chosen sub-systems would be modelled by the method of finite elements, seems to be the most reasonable solution.
