,Validated Finite Element Models Representing Components Building Up the Technical Division’s Substronents have been shipped to the ones that have shown interest in participating in the exercise. The idea of the exercise is to compare different strategies to tackle an experimental substructuring task, containing both decoupling and coupling, thereby learning from each other..In the exercise, the p

Linear Joint Identification for Frictional Rotor Shaft-to-Hub Connections Using Frequency-Based Sube dynamics are projected in a collocated connection point in 6 degrees of freedom, and quasistatic and dynamic substructuring is used to isolate the connection element. Stiffness is identified from the isolated joint. The methodology is validated by comparing resynthesized FRFs on the test structure

Modeling Bolted Joints in the S4 Beam at Various Preloads with Discrete Iwan Elements, bolts when those bolts have a range of different preloads. Measurements were acquired from the S4 beam [Singh et al., IMAC, 2018] at various preloads and with a few permutations of the preloads. A finite-element model was then created with rigid-bar spiders that reduce the joint to a single pair of
