Vertical and lateral horizontal forces of walking area running pedestrians

The authors have noticed the newest observations and few analysis of excitation mechanism. Therefore they prepared the series of vertical and lateral forces measurements due to steps of walking, running persons on horizontal plane, on inclined plane and on stairway. They suppose that the import knowledge of the forces frequencies of step or strides for different walking velocities is the most important for the further analysis and analysis of the mechanisms. The time histories of lateral forces of a pedestrian were registered and statistical analyzed: the authors received the lateral force dependence on the walking velocity, on stride length an on the weight of pedestrian. The new research step is focused on lateral horizontal forces.
