Stability of Follower‐Force Rods with Weight
Publication: Journal of Engineering Mechanics
Volume 110, Issue 3
Abstract
The effect of follower forces and weight on the stability of elastic rods is studied using the 2‐mode Galerkin method. Stability boundaries are presented to show how various combinations of the loads lead to divergence or flutter instability. Results are presented for pinned‐pinned rods, clamped‐free rods and free‐free rods. The free‐free rod corresponds to a flexible missile with distributed follower forces due to drag and weight‐like forces due to thrust. It is shown that a good choice of mass distribution can eliminate flutter instability for all practical loading situations.
