The review paper discusses numerical human body models of pedestrians. The background of current trends in physical and mathematical pedestrian research is presented. Development, validation and areas of application of pedestrian body models are described. The differences between multibody models and finite element models are presented. Accident-based and experimental approaches to validation of the models are discussed. As a novelty, this paper presents an overview of multibody models used in forensic investigations, discusses their usefulness, and differences between their design and the design of more advanced multibody and finite element models. Finally, the most recent trends in human body modelling are discussed, including open-source approaches to model distribution and replacement of physical tests by digital simulations.

Celem artykułu jest opis numerycznego, wielobryłowego modelu ciała człowieka CYBID Multibody Pieszy wprowadzonego w oprogramowaniu V-SIM 5.0. Przedstawiono założenia dla geometrii modelu oraz krótki opis działania generatora ciała człowieka. Omówiono pokrótce dodatkowe funkcjonalności rozwinięte w trakcie procesu wdrożenia modelu pieszego, m.in. interfejs skryptowy do programu V-SIM 5.0. oraz rozszerzone modele wspomagające analizę obrażeń. Przedstawiono także pokrótce kierunki dalszych prac badawczych na potrzeby rozwoju modelu. CYBID Multibody Pedestrian model. Specification, human body generator, research and development of the model The aim of the article was to provide a thorough description of CYBID Multibody Pedestrian model in keeping with its implementation in the commercial version of V-SIM 5.0. reconstruction software. The description of the model geometry and the human body generator is provided together with a detailed explanation of the contact algorithm implemented in V-SIM 5.0. New functionalities including the script interface developed in the process of the pedestrian model implementation in V-SIM 5.0 and extended human body models supporting injury analysis are briefly discussed. Perspective for further development of Multibody models in future V-SIM versions is also presented.
