Studies of numerical simulation and experimental validation are carried out on the planar orthogonal braided composites cantilever beam. On the basis of single-cell model, the model of 1 × 1 orthogonal braided fibre structure is established with the SolidWorks engineering drawing software. Six different loading models are analysed using the finite element software ANSYS. The effective elastic constants are obtained with the homogenisation theory. The finite element model of a cantilever beam is then established, which is made of orthogonal braided composites, where the angle between fibre orientation and periphery varies from 0° to 90°. The experiment is carried out and the natural frequencies are obtained using the free vibration measuring method. The effects caused by the additional mass of sensor are eliminated according to vibration theory, and the results are consistent with those obtained by numerical simulation. [ABSTRACT FROM AUTHOR]
