Application of tire dynamics to aircraft landing gear design analysis [PDF]
, 1983 The tire plays a key part in many analyses used for design of aircraft landing gear. Examples include structural design of wheels, landing gear shimmy, brake whirl, chatter and squeal, complex combination of chatter and shimmy on main landing gear (MLG ...

HyLPD Digital Twin Control for UAV Stability in High‐Wind Conditions
Optimal Control Applications and Methods, EarlyView.This work introduces a novel HyLPD, a hybrid control framework combining Linear Quadratic Regulator (LQR) for baseline stability and Deep Deterministic Policy Gradient (DDPG) for adaptive compensation, tailored for UAVs under high‐wind conditions.

Effect of Cross Transfer Function on Chatter Stability in Plunge Cutting
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010 An accurate analytical model for regenerative chatter vibration in plunge cutting is proposed. Effects of the cross transfer function and the cutting force ratio on chatter stability are considered in the proposed model.

Experimental study of thin part vibration modes in machining [PDF]
, 2008 The machining of thin walls generally generates milling chatter, that damage surface roughness and manufacturing tools. Stability lobes which include natural frequencies are successful in case of tool chatter.

Applying Dynamics/Cost Parameter Continuation to the Optimal Guidance of Variable‐Speed Unicycle
Optimal Control Applications and Methods, EarlyView.(a) Classical parameter continuation method diverges. (b) Dynamics/cost parameter continuation method converges. ABSTRACT The problem of a variable‐speed unicycle guidance to the stationary target is considered. The vehicle should be guided to the origin while minimizing the energy loss due to the induced drag.

Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, EarlyView.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

Integration of dynamic behaviour variations in the stability lobes method: 3D lobes construction and application to thin-walled structure milling [PDF]
, 2006 Vibratory problems occurring during peripheral milling of thin-walled structures affect the quality of the fin- ished part and, to a lesser extent, the tool life and the spindle life.

Cooperative human signals to honeyguides form local dialects
People and Nature, EarlyView.Abstract Human language enables the exchange of complex information and precise instructions for collaborative planning and action. It rapidly evolves through social learning, generating diverse cultural communication signals used not only with other humans, but also with domesticated animals bred or trained to respond.

A review of chatter suppression in thin-wall milling: strategies, mechanisms, and applications
International Journal of Extreme ManufacturingThin-walled parts have been widely employed as critical components in high-performance equipment due to the high specific strength and light weight. However, owing to their relatively weak rigidity and poor damping properties, chatter vibration is likely
