Abstract

Abstract: In this paper, based on one composite oar hub, the finite element modal of the hub structure was established with ANSYS. Through the model simulation and calculation, the modal shape and vibration characteristics were obtained, and the model was confirmed by modal experiment. With this analysis, the dynamic characteristics of the hub was known. It provides reference for further kinetic studies and optimization to the composite hub.

Key words: hub of helicopter, composite material, reverse engineering, finite element method, modal analysis
