In-house multibody human model based on Euler parameters for the fast impact scenario calculation

Popis výsledku v původním jazyce

Purpose of this paper is to build an in-house spatial model of a human body based on multibody approaches, that could be utilized in numerical simulations of various impact scenarios. The model currently contains 17 rigid bodies and 16 spherical joints. The joints are modelled as range-unlimited in order to keep model robust for the further analysis. The limits of the motion will be further modelled within internal stiffness. The concept of four Euler parameters instead of widely used three Euler angles is used. The dimensions and masses of the particular segments are based on the real data of the Czech population measurement in 80s. The model is parametrized with the height and weight of the particular human. All the dimensions are calculated with respect to these values, which makes the model scalable to capture human population diversity. The contact problem of the human body with the external shape or self-contact between segments is solved using the continuous contact force model, where normal and tangential forces are evaluated as a function of the penetration, stiffness and coefficients of restitution. Algorithm for ellipsoid-to-plane contact is applied here. MATLAB software is used to build the in-house software for a human body model.
