TLDR
A dynamic model of a rotating Cartesian manipulator with a payload whose center of gravity doesn’t coincide with the point of attachment is developed to determine the modal parameters i.e., natural frequency and corresponding mode-shape of the manipulator.Abstract:
Here, investigation to explore the effect of generic payload and externally applied asymmetric load on the calculation of modal parameters and dynamic performance of a rotating flexible man...read more

Dynamic modeling and extended bifurcation analysis of flexible-link manipulator
TL;DR: The outcomes indicate that when there is no offset, the decrease in damping results in chaotic generalized modal coordinates, and as the excitation frequency decreases, a limiting amplitude is created at 0.35 before which the behavior of generalized rigid and modal coordinate is different, while this behavior has more similarity after this point.

Shifu Xiao,Bin Chen,Qiang Du +2 more
TL;DR: In this paper, a nonlinear dynamic model of a cantilever beam with tip mass in a centrifugal field is established by adopting the general Hamilton's variational principle, and the dynamic behavior of the flexible component can be affected by the overall motions of the system and the geometrical and physical parameters of the tip mass.
