The study presents an analysis of the impact of selected structural parameters in umprung industrial vehicles on their longitudinal oscillations. It was conducted on the basis of a simplified, linear, two-dimensional model in the form of a parametric spectral transmittance. Transfer function was developed on a number of simplifying assumptions, of which the more significant ones include: the assumption of small oscillations, the assumption that wheełs are in constant contact with the ground, lack of the impact of the horizontal components of the input on the vehicle dynamics, lack of the impact of the wheel slip and the drive system on the vehicle dynamics, single-point contact of the wheels with the ground etc. The qualitative correctness of the obtained results was partly verified by means of computations using a more complex simulation model of a vehicle by means of the MSC.Adams system. The conducted analyses demonstrate that structural parameters such as the moment of inertia and the value of the tir e damping have a crucial impact on the intensity of longitudinal oscillations in unsprung industrial vehicles. The impact of the oscillation coupling coefficient and the mass is significantly smaller.
