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, 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.

Torsional Stiffness of Extended and Plectonemic DNA. [PDF]
Phys Rev Lett, 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.

Evaluating the cutaneous involvement in scleroderma: torsional stiffness revisited [PDF]
Rheumatology, 2001 The pace, progression and extent of the skin lesions in scleroderma may parallel the risk of new internal organ involvement and the progression of existing internal lesions. Accurate assessment of cutaneous change permits an evaluation of patient prognosis and the response to therapy.
