Stability of hollow shafts in torsion

Strength of Materials, 1984
1. The static load capacity of thin-walled shafts is determined by their loss of stability in torsion. 2. A method is suggested for calculating the stability of hollow smooth shafts and shafts with holes in torsion, with axial forces and centrifugal loads taken into account. 3.

TORSION OF A HOLLOW TAPERED SHAFT

Journal of the American Society for Naval Engineers, 1940
The author presents an exact solution of the problem of torsion of a hollow tapered shaft. He attains an order of accuracy hardly required for engineering purposes. The solution is presented as of possible academic interest to some members.

Fatigue failure of a hollow power transmission shaft

Engineering Failure Analysis, 2002
A micro/hairline crack was noticed on a low speed, hollow shaft of a single stage helical gearbox during service. Though this had not resulted in a catastrophic failure, the shaft was withdrawn from service because of leakage of oil. Subsequent investigation revealed that the crack had initiated by fatigue at one of the keyway edges and progressed ...

Elastoplastic torsion of hollow FGM circular shaft

2015
In many cases, a torsional shaft may be a thick-walled radially inhomogeneous cylindrical object. The hollow shafts made of functionally graded materials (FGMs) are such kind of compositions which were studied in this paper. Cylindrical FG shafts are composed of ceramic and metallic parts with power function distribution across the radial direction ...

FEA-optimized lightweight hollow shafts for the transmission

ATZ worldwide, 2009
When it comes to transmissions, considerable weight savings may be made by using hollow transmission shafts. Hirschvogel achieved success in transferring the same high loads in spite of less material use. These forged light- weight shafts may be used both in manual transmissions as well as in axle drives and transfer gearboxes of passenger cars or ...

Scaling of magnetically levitated homopolar hollow-shaft machines

2013 IEEE 10th International Conference on Power Electronics and Drive Systems (PEDS), 2013
In this paper, we analyze scaling issues that arise when the size of a magnetically levitated hollow-shaft machine is varied, but the output power is kept constant. Reducing the size by a factor of two leads to a required increase in speed by a factor of about three.

Torsional Vibrations of a Nonprismatic Hollow Shaft

Journal of Vibration and Acoustics, 1989
Propagation of torsional waves in elastic homogeneous non-prismatic hollow shafts is investigated. Three different types of end conditions are considered: both ends fixed, both ends free, and one free—one fixed end. Design charts are presented to determine the natural frequency of a nonprismatic hollow shaft upon specifying its geometric profile, end ...

VIBRATION OF STRAIGHT–CURVED–STRAIGHT HOLLOW SHAFTS

Journal of Sound and Vibration, 2000
Abstract This work presents the governing equations for both the in-plane motion and out-of-plane motion of a curved hollow shaft. Two types of shaft structures, which are a curved hollow shaft and a straight–curved–straight hollow shaft, are considered.

New warm forming processes to produce hollow shafts

Journal of Materials Processing Technology, 2001
Abstract In order to maintain their competitiveness, the producers constantly have to reduce their costs and to improve the quality of their products. The trend towards lightweight construction in vehicle manufacturing results in an increased use of hollow shafts in vehicle gear boxes.

Analytical Modeling of a Material Efficient Hollow Shaft Design

Advanced Science, Engineering and Medicine, 2020
This paper discusses the optimal distribution of material across the cross-section of a shaft under pure uniform torsional loads such that the factor of safety and thereby the shear stresses generated at any point in the cross-section remain largely the same irrespective of their radial distance from the centre of the shaft. An analytical mathematical
