Abstract
Analysis and design of composite helicopter landing gears are challenges. Cross tubes of helicopter landing gears consist of straight tubes at the middle and curved tubes at the sides. In this work, to simulate ground handling, thick laminated composite straight tubes subjected to pure bending moments are studied using a new high-order simple-input analytical method. The accuracy of the proposed method is subsequently verified by comparing the numerical results obtained using the proposed method with finite element method and experimental data. The results show good agreement. High efficiency in terms of computational time is achieved when the proposed method is used as compared with finite element method. In addition, a simple non-dimensional coefficient is proposed to predict interlaminar radial stresses of thick composite straight tubes.
