Accurate rigid body property (RBP) identification is desired in various industrial fields such as aerospace and automotive engineering. In a past study, we developed a new method based on a model using suspension on a single elastic wire. However, it is often impractical to suspend the test structure on only a single wire. Therefore, to facilitate practical testing, this paper proposes a multi-wire suspension model. In addition, a method that combines the suspension model with modal curve fitting is proposed in order to identify accurate RBP of low-rigidity structures. The effectiveness is demonstrated using two experimental structures.
