N2  - This article presents a three degrees of freedom half car model used for investigating solid axle dynamics. The model used is capable of taking into account the following criteria: seat; the influence of weight; and lateral input. It is described by the symbolic method, ie complex stiffnesses and complex amplitudes of time dependent values are used to compile the equations of motion. This means that a smaller number of equations are needed, and that the stiffnesses, especially the lateral stiffness between the vehicle wheel and the road surface, can be included in the design. Only harmonic vibrations are dealt with. A statistical form of road unevenness (the Road vertical input), namely the spectrum of the antiphased unevenness, and Lateral input in the form of an impulse of the centrifugal force, are used to obtain five output criteria. These output criteria are in the form of frequency characteristics of "impulse-effective" values. Only roll is modelled. The results obtained indicate that when there is lateral input (ie when cornering), the solid axle has a clear advantage over independent suspension. However when travelling in a straight line at low speeds, independent suspension is more favourable.<p />
