The paper introduces the new application method of ICA on vehicles' vibration considering dynamical properties and examines the performance through a model experiment. Vertical accelerations on body frame are measured and integral, double integral, differential and double differential of accelerations are calculated. Those signals are considered observed signals as well as measured accelerations. Original ICA is meaningful in the separation of mixed complex signals, and authors' proposing method realizes consideration of dynamical properties. To check the separation performance, two different types of vibrations are excited from the bottom of the model. Then, ICA is conducted with the vertical acceleration signals and the other calculated signals. As a result, two different signals which have similar frequency feature are separated with proposing method.
