More efficient tuning for ride comfort requires better predictability of vibrations of a full car under driving conditions. The ride comfort in passing over bumps is often affected by low frequency vibrations of several sub-systems such as engine/transmission, body, and knuckles connected by vibration elements such as mounts, shock absorbers and tires. Hydraulic base excitation is a powerful technique by which excitations on a full car can be performed indoor either for vibration characterization or performance evaluation. In this paper, a 10-degree of freedom lumped parameter model for a full car is constructed for simulation studies based on the vibration characteristics obtained from the base excitations. Some problems and findings in such dynamic modeling based on base excitations are presented.
