Research on the Marine Shafting Torsional Vibration with Gears Transmission
Abstract The torsional vibration of marine propulsion shafting has been studied for more than a century. With abundant research achievements and experiences, a systematic approach of vibration calculation has been put forward for ship industrial applications. However, literature review indicates that when processing the gear transmission in the shaft line, the meshing motion has been treated as...
متن کاملWhole-blade Propeller Dwi
Introduction PROPELLER [1] is a variant of multi-shot FSE technique, providing a high-resolution DWI with excellent immunity to offresonance. Its self-navigated nature around the center of K-space also allows for motion correction. The odd/even echo phase inconsistencies in the non-CPMG echo train were addressed using the “split-blade” method [2], where the blade width was reduced by a factor o...
متن کاملApplication of Torsional Vibration Measurement to Blade and Shaft Crack Detection in Operating Machinery
The primary goal of the this paper is to summarize field demonstrations of the feasibility of detecting changes in blade and shaft natural frequencies (such as those associated with a blade or shaft crack) on operating machinery using non-contact, nonintrusive measurement methods. This paper primarily addresses the results of application of this nonintrusive torsional vibration sensing to: a la...
متن کاملBlade and Shaft Crack Detection Using Torsional Vibration Measurements Part 3: Field Application Demonstrations
The primary goal of the this paper is to summarize field demonstrations of the feasibility of detecting changes in blade and shaft natural frequencies (such as those associated with a blade or shaft crack) on operating machinery using non-contact, nonintrusive measurement methods. Laboratory demonstration of feasibility and some special signal processing issues were addressed in Parts 1 and 2 [...
متن کاملLongitudinal Magnetic Field Effect on Torsional Vibration of Carbon Nanotubes
Torsional dynamic analysis of carbon nanotubes under the effect of longitudinal magnetic field is carried out in the present study. Torque effect of an axial magnetic field on a carbon nanotube has been defined using Maxwell’s relation. Nonlocal governing equation and boundary conditions for carbon nanotubes are obtained by using Hamilton’s minimum energy principle. Eringen’s nonlocal stress gr...
