Abstract :
In the paper a procedure for real-time detection of low frequencies is proposed, and it is customized for detecting very low frequency and slightly higher frequency components. The case study is focused on the observation of a Magnetorheological suspension system installed on a commercial motorbike: the resonance frequencies due to the sprung mass and due to the unsprung masses are monitored. Tests were made on actual signals acquired during the normal motorbike running.
