Application of Experimental Spatial Matrix Identification to An Actual Vehicle Chassis

The theory of a new experimental spatial matrix identification was proposed previously by one of the authors with a basic application. In addition, in this paper, its practical application to an actual mechanical structure is presented, since the authors think that it is important to investigate the practical validity and the usefulness of the identification method by its application to actual mechanical structures. The actual mechanical structure to be identified in this paper is an actual vehicle's chassis. In addition to showing this successful identification, some techniques to be considered for succeeding the identification are discussed with simulation based identification results: the identification of a vehicle's chassis model and cabin model, and the prediction of the dynamic characteristics of their assembly system.
