Numerical modeling of nonlinear viscoelastic vibrations of vehicles

Nonlinear viscoelastic oscillations of a vehicle in vertical direction excited by static imbalance are considered. When taking into account the rheological properties suspension material and spring, Boltzmann-Volterra principle was used. Mathematical models problem under consideration obtained, which described systems nonlinear integro-differential equations. A solution method based on quadrature formulas has been developed, computer program compiled its basis. The results obtained reflected graphs. influence material's characteristics spring amplitude frequency vibrations vehicles investigated.
