Modal degeneracy and oblique bending modes in ultra-long cable-strut deployable space masts

Siyi Meng, Suxia Zhang, Zhiqiang Wu, Biao Li et al.

Short summary

A prestress-dependent transfer matrix model reveals that local stiffness reductions or asymmetric tip masses break symmetry in ultra-long cable-strut space masts, lifting modal degeneracy and inducing oblique bending modes.
