FIRE TRUCKS EXTREME ACCELERATION AND BRAKING DYNAMICS

Abstract

The research provides facts that confirm the utmost importance of the dynamic properties of fire trucks. The model description of the dynamics of longitudinal rectilinear movement of fire vehicle was presented. Based on this description in the most general analytical form the necessary and sufficient factors of fire trucks’ extreme acceleration and braking dynamics were determined .It is noted that the traditional extreme dynamism is associated with the implementation of the maximum
adhesion with the road. Instead, it is shown that the optimal wheel slip does not always depend on maximum value of the coefficient of adhesion with the road. Therefore there is a need for a more profound study of the opportunities to intensify the process of acceleration and deceleration.
