I want to calculate stiffness and damping of floating ring seals for rotordynamic analysis. Is there any paper with acceptable results in comparison to experimental results in this regard?
Dear all,
I want to calculate rotordynamic coefficients for ball bearings.
I saw a report by A.B Jones in this regard including a code.
But this code can not be copied.
Does have anyone this code?
I used OCR but it doesnt work correctly.
Dear,all
I want to do a transient analysis with ansys.
time duration: 3400s
But I get unconvergence problem after 40 or 50 second with 0.1 time increment and 600 second with 5 time increment (time step)
What is the problem or how can I guess the problem?

Dear all
in thread384-202775 is a transient analysis in ansys for a rotor
but in ansys when rotational speed changes, we should update rotational speed with frequency of unbalance force.
in harmunic analysis in ansys the command syncro does this.
In transient analysis in one...
Dear all,
I want to do a run- up analysis for a rotor in ansys. The rotational speed change from 0 to 5000 rpm
In ansys help is explained:
nlgeom,on !! so that the gyroscopic matrix is updated
But because my model has Combin214 element, the nlgeom make error and solve dont run.
when I remove...
Hello,all
I want to do two analyses:
1- interaction between rotor-fluid in gas turbine for rotordynamic analysis
2- interaction between a fan and fluid. Some part the fan is inside the fluid and some out of it. for this case I have the profile of load on the fan. Do I need to do a...
Hello,all
I want to do a rotordynamic analysis.For this end, I used
a 3-d part model and want to extract a 2-d axisymmetric model from 3-d model. I imported 3-d model into workbench.
I know that it is possible but now I can't do that.
I used "freeze" in workbench but I don't know exactly what...
