[Analysis Case] Analysis of Stray Losses in Power Transformers

Analyze stray load losses under the condition of the presence or absence of leakage flux blocking components in the transcoil!

We would like to introduce the "Analysis of Power Transformer Stray Losses" conducted by our company. The analysis mode is frequency response analysis (Time Harmonic), and the rated capacity of the power transformer is 100 MVA. The input frequency is 50 Hz/AC. As a result of the analysis, it was found that the leakage magnetic flux generated from the transformer coil is significantly and extensively collected at the shunt wall. 【Analysis Conditions】 ■ Analysis Mode: Frequency Response Analysis (Time Harmonic) ■ Power Transformer Rating: 100 MVA ■ Input Frequency: 50 Hz/AC ■ Shunt Wall (Flux Collector): Magnetic Material ■ Frame Material, Tank Material: Carbon Steel *Details of the case can be viewed through the related links. For more information, please feel free to contact us.

FEMFAT laminate: Fatigue strength analysis of continuous fiber reinforced resin

It is possible to analyze the fatigue strength of each layer of continuous fiber reinforced resin under multi-axial loading.

FEMFAT laminate is a module for fatigue analysis of continuous fiber reinforced resins (available in ChannelMAX). Within the MAX module, fatigue strength evaluation can be conducted individually for each laminate. The front and back sides of each laminate in the composite material are subject to damage calculation. The analysis method is adapted to the laminate material using the stress types of "Critical Component in Critical Plane," evaluating fiber breakage and interlayer breakage within the fibers. Furthermore, when using a solid element model (typically 8-node hexahedral elements), delamination can also be assessed. For damage calculation, static strength characteristics (tensile strength and compressive strength) and fatigue strength characteristics (S-N curves) are required for loads in the parallel and perpendicular directions to the fibers, as well as for shear loads in the laminate plane. It supports shell and solid elements defined with COMPOSITE properties using Abaqus inp files and odb files. *For more details, please download the PDF or contact us.*
