Defining bearing in UCS analysis

[SquawkCodeVFR]

Hello,

When using the UCS analysis for variable bearing stiffness, is there any possibilty in defining which bearing should be used for the calculation?

I have a rotor with two bearings and I would like to keep the first bearing at a constant stiffness and the second one should be used
with variable stiffness for the UCS calculation.

Thanks for your help!

Hi @SquawkCodeVFR !
To do that you would need to modify the code in the rotor_assembly.py file, changing how the bearings list is built:

ross/ross/rotor_assembly.py

Lines 2188 to 2196 in 3895ca6

	bearings_elements = [] # exclude the seals
	for bearing in self.bearing_elements:
	if not isinstance(bearing, SealElement):
	bearings_elements.append(bearing)
	for i, k in enumerate(stiffness_log):
	bearings = [BearingElement(b.n, kxx=k, cxx=0) for b in bearings_elements]
	rotor = self.__class__(self.shaft_elements, self.disk_elements, bearings)
	speed = 0

Thank you so much! It worked for me with the following changes:
