Torsional Vibrations in a Mechanical Drive

SAE Technical Paper Series, 1982
<div class="htmlview paragraph">Torsional vibrations of an engine-powered hydraulic system were analyzed. The system consisted of: a diesel engine, spline shaft with clearance, universal joints, propeller shaft, mechanical transmission with clutch engagement, hydraulic pump, and a load. Excessive torsional vibrations resulted in propeller, spline

Mechanisms of testicular torsion and potential protective agents

Nature Reviews Urology, 2014
Testicular torsion is a urological emergency most commonly seen in adolescence, involving a decrease in blood flow in the testis resulting from torsion of the spermatic cord that can result in gonad injury or even loss if not treated in time. Testicular ischaemia-reperfusion injury represents the principle pathophysiology of testicular torsion, with ...

The Relevance of Torsion to the Mechanical Derangement of the Lumbar Spine

Spine, 1981
Cadaveric lumbar intervertebral joints were loaded simultaneously in torsion and compression, and load-deformation curves were obtained. These were repeated after each of the following structures were cut through in turn: the supra/interspinous ligaments, the apophyseal joint in compression, and the apophyseal joint in tension.

Algorithm for design of compliant mechanisms for torsional applications

2014 IEEE/ASME International Conference on Advanced Intelligent Mechatronics, 2014
Compliant mechanisms have been widely used in various mechatronics and robotics applications as they offer several significant advantages like repeatability and non-existence of backlash. The designs of these compliant mechanisms are often based on experience and intuition, and can be a frustrating experience during the design phase.

Torsional Buckling of Shafts Coupled By Mechanisms

Journal of Sound and Vibration, 1994
Abstract The paper is concerned with torsional buckling of a system composed of two parallel shafts coupled together by two mechanisms. The motion of the system is described by a set of non-linear differential equations with coefficients which are periodic functions of displacements. Fixed points, closed orbits, homoclinic and heteroclinic orbits and

Modelling of a torsion-bar cam mechanism

Mechanism and Machine Theory, 1993
Abstract In high-speed disc-cam mechanisms, vibration of the linkage is harmful in that the end motion deviates from the required schedule; but more importantly, the vibration may result in the loss of contact between the cam and the follower. This causes an increase in noise levels and excessive wear.

[Pathophysiological mechanisms of torsion dystonia].

Patologicheskaia fiziologiia i eksperimental'naia terapiia, 1989
Sixty-three patients were subjected to clinico-electrophysiological examination for precise definition of the features of pathogenesis of the tonic and clonic forms of generalized torsion dystonia. Stimulation electromyography was conducted by the generally accepted method with determination of the composition of motor neurons involved in the reflex ...

TORSIONAL VIBRATIONS OF THE DRIVE SHAFTS OF MECHANISMS

Journal of Sound and Vibration, 1997
Abstract A study on the torsional vibrations of the drive shafts of mechanisms having variable inertia has been presented in a previous paper by the authors. The drive shaft has been assumed to be a continuous element with distributed mass. Continuous element modelling of the shaft leads to a different mathematical formulation. In this previous paper,
