Hi,
I am studying the rapid deceleration of a turbo rotor during a catastrophic failure and I need to develop a hand-calc analysis method to help assess the results from tests.
The turbo product is about 150mm dia by 200mm tall. The 1.2Kg rotor spins at 60,000rpm and when it fails it stops in...
Hi all,
I am measuring bearing vibration and I have been told by a colleague that twice running speed responses are indicative of a bearing fault, particularly due to misalignment or inadequate preload.
The bearing is a deep groove ball bearing with a predominant axial load and runs at a very...
Hi,
I have a precision shrink-fit rotor assembly that features a shaft with a stack of heated aluminium hub discs (~150mm dia) that are press-fitted onto a LN2-cooled shaft. We are left with small gaps remaining between the discs (shrink-back) and the measurement of these is critical for our...
I'm struggling go to find the formula to calculate the stress & strain developed along a beam that is rotating around one end (simple rotor blade). Roarks give a simplified calc for max stress/strain in a pinned beam, I need to know the stress as it develops from the tip inwards.
Does anyone...
We have a bearing failure and this has led to one adjacent component becoming coloured - straw colour with some blue hue.
Does anyone know the correlation of different stainless steel colours with temperature. I tried checking my annealing literature but could not find anything.
Thanks
