The torsional stiffness of involute spur gears

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2004
This paper presents the results of a detailed analysis of torsional stiffness of a pair of involute spur gears in mesh using finite element methods. Adaptive meshing has been employed within a commercial finite element program to reveal the detailed behaviour in the change over region from single- to double-tooth contact zones and vice versa.

Axial and torsional stiffness of pediatric prosthetic feet

Clinical Biomechanics, 2017
Prosthetic stiffness likely affects the walking biomechanics of toddlers and children with leg amputations, but the actual stiffness values for prostheses are not reported by manufacturers or in standardized testing procedures.We measured axial (kA) and torsional (kT) stiffness from four brands of pediatric prosthetic feet (Trulife, Kingsley Mfg.

Torsional stiffness of reinforced concrete members subjected to pure torsion

Magazine of Concrete Research, 1972
Synopsis A method is described for determining the torsional stiffness at the cracked stage of reinforced concrete members subjected to a pure torsional moment. The method is based upon a truss analogy for torsion. Theoretical expressions are deduced for the Torsional stiffness of beams of arbitrary and rectangular cross-sections.

Torsional Stiffness of Embedded Footings

Journal of the Soil Mechanics and Foundations Division, 1971
Numerical values of torsional spring constants with corresponding stress and displacement distribution are obtained for circular footings for various embedment. The presence of rigid discs (thin rock layer), and voids (loose soil pockets), below the surface are considered, and torsional stiffnesses are obtained. The stress distribution around a footing

Study on Torsional Stiffness of Engine Crankshaft

2009 International Forum on Computer Science-Technology and Applications, 2009
Many empirical formulae are used to calculate torsional stiffness of Engine Crank, but discrepancy exists between these calculation results. In this paper, in order to obtain a more precise result, the modified Ker Wilson formula and Carter formula were employed to calculate torsional stiffness of engine crankthrow in the case of different thickness ...

Contribution of the musculature to rotatory laxity and torsional stiffness at the knee

Journal of Biomechanics, 1987
The relationships between the mean rectified electromyogram (EMG) from two muscle groups crossing the knee joint and the rotational stiffness and laxity about the longitudinal axis of the lower leg were investigated. The EMG signals from three of the quadricep muscle group and two of the hamstring muscle group were monitored using surface electrodes ...

The torsional stiffness of a shaft with an elongated slot

Strain, 1975
An analysis is given for estimating the torsional stiffness of a circular shaft with an elongated slot symmetrical about its centre line. The solution for the stress function is by a finite difference approach and because of symmetry, only one quarter of the cross–section is considered. A non–dimensional graph is presented of the ratio of the stiffness

Torsional stiffness of viscoelastic spheres in contact

The European Physical Journal B - Condensed Matter and Complex Systems, 2004
The theory of elastic contact between two spherical bodies according to Hertz, Mindlin and others is used as a basis for an extension to include the contribution of the viscous effects to the total stress for viscoelastic spheres subjected to twisting moments. Expressions relating twisting moment to the radius of a 'stick' region of the contact surface

Torsional Stiffness of Multicell Hollow Sections

Practice Periodical on Structural Design and Construction, 2001
Torsional stiffness is one of the member section properties commonly used in the 3D finite-element structural analysis. The explicit formulas for the torsional properties in both thin-walled open cross sections and single thin-walled closed sections, except for multicell closed sections, can be easily found in most textbooks and structural design ...
