Abstract
Composite materials have been extensively used in engineering applications over the past few decades. The composite materials present good features over the standard metallic materials that have been used so far. Also, in many mobile systems, the dynamics of the shaft can benefit from the composite materials usage, for their smaller inertias. In this sense, composite shafts demonstrated to be interesting for rotating machines on onboard applications due to the associated low weight and high strength as compared with standard steel shafts. Additionally, composite shafts allow for mechanical properties manipulation by adjusting fiber and matrix composition, layer orientation, layer thickness, and other geometric properties, thus enabling customization capacity. For the modeling of composite onboard shafts, simplified theories are considered. Most theories aim at providing sufficiently accurate vibration responses of the system with low computational cost. In this study, the Simplified Homogenized Beam Theory (SHBT) was explored, associated with the additional considerations for the onboard dynamics representation. The model was simulated for different configurations and its vibration response is presented.
