The article deals with the fluctuations of the fire-rescue vehicle caused by road irregularities and significant impact on its performance: primarily on speed and smoothness. Dynamic vehicle system are treated as equivalent to the oscillating system, and the analysis of dynamic loads is based on systems of differential equations, allowing to investigate the dynamic loads of different types of fire-fighting vehicles, mounted on a 2-axial, 3-axial, and multisupport motor-running the bases.
