    Thin-wall parts are common in the aeronautical sector. However, their machining presents serious challenges such as vibrations and part deflections. To deal with these challenges, different approaches have been followed in recent years. This work presents the state of the art of thin-wall light-alloy machining, analyzing the problems related to each type of thin-wall parts, exposing the causes Cited by: 3.

On the use of a component mode synthesis technique to investigate the effects of elastic boundary conditions on the transmission loss of baffled plates.

Based on free interface component modal synthesis method, the free vibration behavior of wind turbine structures is investigated. The wind turbine structure is divided into three parts including tower, wheel hub-cabin and rotor.

The tower is modeled as an isotropic metal cantilever beam, the blade as thin-walled composite beam and the wheel hub-cabin as a rigid body due to its large Cited by: 2.

Rotordynamics investigation of rotating components of chiller assembly can be accelerated by using advanced techniques such as component mode synthesis (CMS).

Chiller assembly results from modal and harmonic analyses are. Destabilizing forces in compressors extract energy from the process gas and rotation to excite a rotor vibration mode (usually the first forward whirling mode). If these forces grow large enough and overcome the damping forces in the rotor system, the vibration amplitude of that mode will grow unbounded until a rotor-stator rub occurs.
