Numerical Investigation on Torsional Mode Self-Excited Vibration of Guide Vane in a Reversible Pump-Turbine during Pump Mode’s Starting Up [PDF]

Journal of Applied Fluid Mechanics, 2022
In reversible pump-turbines, guide vane vibrations are considered to have potentially severe consequences of noise and structural damage. Unstable torsional mode self-excited vibrations of guide vanes have been reported at small guide vane openings ...

An Internal Resonance Based Method for Reducing Torsional Vibration of a Gear System

Machines, 2022
The gear system is one of the most widely-used transmission systems due to its accurate transmission ratio and high efficiency. However, torsional vibration may severely degrade transmission performance and shorten the gear lifespan.

Static Behavior of Circular Section CFRP Concrete-Filled Steel Tubes Under Compressive–Torsional Load

Frontiers in Materials, 2022
In order to study the compressive torsional behavior of concrete-filled CFRP steel tubes (CF-CFRP-STs), the static test of eight circular section CF-CFRP-ST compression torsional specimens was carried out.

Torsional Stiffness Comparison of Different Tube Cross-Sections of a Formula SAE Car Space Frame

MATEC Web of Conferences, 2018
Since torsional loading and the accompanying deformation of the frame and suspension parts can affect the handling and performance of the car, torsional stiffness is generally thought to be a primary determinant of frame performance for a FSAE car ...

Optimization methodology for control strategy of parallel hybrid electric vehicle based on chaos prediction

AIP Advances, 2018
Irregular internal excitation (engine excitation and motor excitation) and external excitation (road excitation) can cause torsional vibration which even leads to the break of shaft of parallel hybrid electric vehicle (HEV) powertrain.

Application of Concrete Segment Panels for Reduction of Torsional Vibration Responses of Girder Bridges

MATEC Web of Conferences, 2015
The dynamic flexural behaviour of railway bridges is influenced by the torsional behaviour, and the flexural response tends to be amplified as the flexural natural frequency (the 1st vibrational mode) and torsional frequency (the 2nd vibrational mode ...

On a mechanism for enhancing magnetic activity in tidally interacting binaries [PDF]

, 2002
We suggest a mechanism for enhancing magnetic activity in tidally interacting binaries. We suppose that the deviation of the primary star from spherical symmetry due to the tidal influence of the companion leads to stellar pulsation in its fundamental ...

Contribution of Torsional Vibration Modes and the Influence on Period Ratios in the Seismic Response of Elastic Plate Bent Frame Structures

Buildings
The structural characteristics of large-span structures inherently differ from those of conventional multistorey structures, making it challenging to accurately describe the contribution of various vibration modes to the overall response using ...
