As an indispensable component of the ship, marine shafting system transmits power generated by the main engine to the propeller, and at the same time transmits propeller thrust to the hull, and therefore drives the ship ahead. Torsional vibration does lots harm to ship shaft system, brings a serious threat to the safe navigation of the ship. The method of power flow considers the amplitude and phase...
The objective of this document is to present the structural analysis of the ITER Cryostat. A short description of the Cryostat design and main loads is provided. The Cryostat structural analysis is presented focusing on the strategy of global and local assessments.
A quantitative knowledge of inter-filament transverse resistance will allow us to describe current redistribution processes inside strands more accurately. This is particularly important for the analysis of the influence of strain and crack distribution patterns in Nb3Sn filaments on the shape of the voltage-current curves. Several indirect methods are commonly used to assess inter-filament resistance...
This paper presents a 3D simulation study of the basic propagation of partial discharge (PD) acoustic emission (AE) signals from structures akin to high voltage equipment such as switchgear. Partial differential equations (PDE) describing the signals have been developed and solved using Finite Element Analysis (FEA) rather than Finite Difference Time Domain (FDTD) which has been used by different...
