BIOMECHANICAL MODEL OF BICYCLIST AND NUMERICAL ANALYSIS OF BIKE ACCIDENT IN ASPECT OF CONSEQUENCES FOR HUMAN CERVICAL SPINE

Modelling researches concerning falling down man on the head during bicycle accident and its consequences for human cervical spine are presented in this paper. Studies mainly focus on compression, flexion and extension injuries mechanisms which appear during human body movement in saggital plane. The interaction with environment, the human body behaviour, inertial and external forces have a significant influence on type and scale of spine injuries. In order to analyse correlation between head movement and physical phenomena in the neck, two dimensional dynamical model was created using Working Model 2D professional system. The model allows to analyse internal forces which appear insight human spine and body kinematics in saggital plane. Moreover created model could be used to analysing movement of diving man into shallow water. Research results of numerical simulations allowed to qualitatively estimating the most dangerous conditions for people falling down on the head during bike accident and during jumping into shallow water. KEY WORDS: bicycle accident, neck injuries, modelling, numerical simulation. INTRODUCTION: The spine is functionally one of the most important parts of the huma
