Butterfly disturbance vs butterfly angle before butterfly

2 cases of a centrifugal pump shaft are studied. In the first case fatique of the shaft is studied. The maximum bending stress in the shaft will be determined, caused by impeller imbalance, impeller weight and radial load of the engine. The bending stress must stay below the materials allowable bending stress for fatique of 74 N/mm2. Also the maximum bending of the shaft is important here, which is only allowed to be 50 micrometer at the stuffing box by ISO 9908. The plane of the stuffing box is located at 399 mm from the coupled side of the shaft. For the second case the mechanical strenght of the shaft while undergoing the engines pull-out torque (maximum torque of the engine). This is required to asses the shafts minimal diamater (on which the impeller is attached), so that no plastic deformation will occur. To prevent plastic deformation the maximum stress in this part of the shaft must stay below the materials yield stress of 220 N/mm2.

Tutorial project for linear static analysis of a crane

In this exercise, you will perform a simple heat transfer analysis on the SimScale Platform and then compare the results to a hand-calculated solution.

A comparison between a pipe with probe inserted against only the hole surrounding the probe at 2 different velocities.
The 2 velocities used are 3 m/s and 15 m/s.

In this exercise, you will use linear static analysis to analyze several configurations of an aircraft engine bracket under a vertical load.

Incompressible Fluid Flow analysis of two globe valves

FEA Master Class Session 3 handout: In this project the drop test of an iPhone 6 has been performed with and without case.

This project demonstrates the static stress analysis of three aircraft engine bearing bracket models considering both linear and nonlinear material definition. The models used in this analysis are taken from GrabCAD users who were the winners of GrabCAD 'Airplane Bearing Bracket Challenge'. The models are tested with horizontal and vertical loading conditions as provided on the challenge page of GrabCAD.
