Coupling with adjustable torsional stiffness [PDF]
Proceedings of the Estonian Academy of Sciences, 2021 This study presents a novel coupling design with adjustable torsional stiffness. Since the torsional stiffness of the coupling can be adjusted, it can potentially be applied to tune the torsional natural frequencies of rotating systems.

Dynamic Torsional Stiffness of Reducers and Its Testing Method
Applied Sciences (Switzerland), 2023 The torsional stiffness of the reducer is commonly assumed to be static and tested using the hysteresis curve method. However, practical engineering experience shows that the torsional stiffness is dynamic rather than static, and the hysteresis curve ...

Minimizing the Negative Effects of Coolant Channels on the Torsional and Torsional-Axial Stiffness of Drills [PDF]
Metals, 2021 Coolant channels allow internal coolant delivery to the cutting region and significantly improve drilling, but these channels also reduce the torsional and torsional-axial stiffness of the drills.

DETERMINATION OF TORSIONAL STIFFNESS OF HARMONIC DRIVE [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2014 The aim of this study was to develop a simplified method for determining the torsional stiffness of harmonic drive. For this purpose, in this paper the flexspline of harmonic drive is studied by dividing it into three distinctive portions.

Torsional stiffness of extended and plectonemic DNA [PDF]
Biophysical Journal, 2021 DNA torsional elastic properties play a crucial role in DNA structure, topology, and the regulation of motor protein progression. However, direct measurements of these parameters are experimentally challenging. Here, we present a constant-extension method integrated into an angular optical trap to directly measure torque during DNA supercoiling.

Pipe profile optimization of formula student chassis for torsional stiffness [PDF]
MATEC Web of Conferences, 2023 One of the key aspects of designing a formula student car chassis is torsional stiffness. High torsional stiffness gives stability to the suspension system and provides better handling of the car.

Method for Adjusting Torsional Natural Frequencies of Powertrains with Novel Coupling Design
Machines, 2022 Torsional vibrations are inherently present in every rotating powertrain. In resonant conditions, torsional vibrations can be significantly amplified. A typical method to reduce the torsional vibration particularly at resonance is to modify the torsional

TORSIONAL STIFFNESS AS AN INFLUENCE PARAMETER ON ARCH STABILITY [PDF]
Proceedings of International Structural Engineering and Construction, 2020 Arch bridge springs can be connected to concrete abutments either by prestressing bars or by connectors. In both options, the torsional stiffness is substantially reduced, compared to the full arch cross sectional area. The influence of this lack of torsional stiffness on arch buckling is being researched, both numerically and experimentally. To reduce

Torsional and Transversal Stiffness of Orthotropic Sandwich Panels [PDF]
Materials, 2020 In the present work, an analytical equation describing the plate torsion test taking into account the transverse shear stiffness in sandwich plates is derived and numerically validated. Transverse shear becomes an important component if the analyzed plate or shell is thick with respect to the in-plane dimensions and/or its core has significantly lower ...
