Abstract
The article investigates vibration and noise protection devices for wheeled vehicles
using dynamic vibration absorbers (DVA). Algorithms for modeling their dynamic characteristics
based on adaptive calculation schemes are presented. A non-linear suspension with DVA and a
noise-absorbing partition is considered, which is due to the introduction of a layered composite thinwalled
structure with an intermediate damping layer with high damping properties and a DVA
system, which provides better vibration and noise absorption. The problems of shock propagation
during the overturn of the bus to passengers are also considered. The influence of the parameters of
the shock absorber on the dynamic properties of the bus is investigated. The optimal parameters of
the shock absorber are determined.
