Abstract
Forward falls on outstretched hands are caused by unexpected lost of stability and they are always related with different kinds of injuries. This paper takes attempt to explain and figure out the multifaceted problems of forward fall. In order to estimate the critical value of the force acting on the hands at the moment of impact on the ground, the relative simple mechanical model is proposed. Mathematical model is described by the second order differential equations obtained by the Newton–Euler method, and its parameters are identified and validated using experimental data from one of the recent paper. Some interesting results are obtained, presented and discussed. The presented numerical simulations show that the proposed model demonstrate good accordance with real tested objects presented in the literature. The model predicts the highest impact force and finally allows to simulate various scenarios of human falls.
