THEORETICAL INVESTIGATION ON NON-STEADY-STATE DRIVING CONDITIONS OF A MOTOR VEHICLE

The object of this paper is the investigation of vibrations occurring within the transmission system of a motor vehicle under non-steady-state driving conditions. In particular the process of accelerating a passenger vehicle from standstill will be considered. The vehicle model presented has eight degrees of freedom. In addition particular attention is devoted to the description of the tyre performance by introducing a new tyre theory which makes it possible to calculate non-steady-state longitudinal shear stress distributions along the tyre contact patch of the driving wheels for each point of time within the vehicle's accelerating process. Numerical calculations will be presented for a rear driven passenger vehicle provided with a specific wheel suspension. Peak values of transmitted torques within the driving system will be calculated and the non-steady-state tyre behaviour will be expressed chiefly in terms of the adhesion coefficient and tyre slip.
