Étude Théorique du Shimmy des Roues d'Avion

, 1952
The problem of shimmy of a castering wheel, such as the nose wheel of a tricycle gear airplane, is treated analytically. The flexibility of the tire is considered to be the primary cause of shimmy.

Effect of dual co-rotation wheels configuration on aircraft shimmy [PDF]

, 2015
A mathematical model is developed to study the shimmy oscillations of aircraft nose landing gear with a dual-wheel co-rotation configuration. This model incorporates the dynamics of the torsional and lateral mode and the non-linear kinematics of the tire.

Icing Monitoring of Wind Turbine Blade Based on Fiber Bragg Grating Sensors and Strain Ratio Index

Energies
In cold regions, the power generation efficiency of wind turbines is affected by blade icing. Heavy icing on blades will change the aerodynamic configuration of the blades and can even cause blades to crack or break.

Horizontal Axis Wind Turbine Blade Finite Element Design Modeling with Structure and Vibration Modal Analyses to Optimize Wind Power for Offshore Applications

Sukkur IBA Journal of Emerging Technologies
Offshore wind farms are subject to complex stresses with respect to the wind influence on the turbine blades. When air flows through the airfoil surface of a wind turbine blade's element profile, the relative wind velocity causes the aerodynamic forces (

Experiments on a Tail-wheel Shimmy [PDF]

, 1954
Model tests on the "running belt" and tests with a full-scale tail wheel were made on a rotating drum as well as on a runway in order to investigate the causes of the undesirable shimmy phenomena frequently occurring on airplane tail wheels, and the ...
