Abstract

This paper addresses the need to minimize of vibration levels of unsprung weight of elements of vehicles suspension are considered. In the study design, some methods of parametric optimization with dynamic vibration absorbers (DVA) in elements of a nonlinear suspension with dynamic mechanical properties have been applied. To determine the low frequency components of vibration of laminated composite plates with the DVA system numerical estimates of the vibration of the equivalent plate of Timoshenko used. One structural version for ensuring the preservation of the residual space of the passenger cabin of the bus during the rollover according to norms 66 is considered. The energy-absorbing structure of the roof of the bus is made in the form of tubular space-frame made of composite materials.
