Content
This paper presents some considerations and an application to automotive's subframe concerning system identification method by characteristic matrices using modal parameters to obtain rigid-body properties of mechanical structure. The pendulum method was adopted as the conventional way to identify the rigid-body properties in automotive's engine components such as flywheel. In the case of the big, complex shaped and heavy structural component such as frame and vehicle body, this method is not adequate for the difficulty of building the huge fixture and making sure of the accuracy of identification. So, in this paper, the method identifying characteristic matrices using the modal parameters is applied to automotive's subframe.
