Rotary Speed Modulation to Improve the Stability of Steady Drilling,tant even with periodically varying steady twist of the drill-string has been considered in the current work. We observe the significant improvement in the stability of the system as the modulation frequency reaches towards the natural frequency corresponding to trosional mode.

Comparative Analysis of NES and TMD Performance via High-Dimensional Invariant Manifolds,s: the NES achieve a broad frequency band of operation exploiting nonlinearity, while the TMD by increasing damping. An interesting feature, highlighted by the invariant manifold, is that the NES is generally unable to resonate with more than one mode of the primary system at the same time, rather, it experiences a sort of modal cascade.

Asynchronous Modes of Beams on Elastic Media Subjected to Varying Normal Force: Continuous and Discous model. Classic linear modal analysis for associated finite-element models is addressed for the sake of comparison and to bring about the issue of modal accumulation, which seems to be an accompanying phenomenon to that of modal asynchronicity.

Conference proceedings 202015th to 19th, 2018. .The appearance of nonlinear phenomena used to be perceived as dangerous, with a general tendency to avoid them or control them. This perception has led to intensive research using various approaches and tailor-made tools developed over decades. However, the Nonlinear Dynamics of
