RANDOM VIBRATIONS OF A MULTI-WHEELED VEHICLE
The vehicle considered is a three-dimensional, N-wheeled vehicle. The speed of the vehicle is assumed constant, and it is also assumed that the wheels maintain ground contact at all times. The suspension system is assumed to be a simple spring-viscous damper system connected in parallel. The spring and damping constants can be varied from wheel to wheel or can be held constant. Power spectral densities are derived for the vertical acceleration of the mass center and for the pitch and roll accelerations of the vehicle. The power spectral density is also determined for the vertical acceleration of any point not at the mass center of the vehicle. The input for the aforementioned equations is the power spectral density of the traversed terrain.
