Hi everybody,
i've a problem with an explicit analysis, dealing with a 2D cylindrical roller bearing working as track roller.
The model is "simple": the inner ring is fixed in its own position, and the rigid surface is pushed against the outer ring.
My problem is that i've set the force...

this is what i get by .msg file:

Hi all
I'm dealing with the problem in object: usually we use standard method (ISO) to estimate L (number of revolution before collapse), but now we are looking for a better solution.
I'm totally out of concepts about fatigue analisys in abaqus, does anybody can provide something? The boss...
Hi
i've a bearing with inner ring fixed at position and outer ring rotating at a speed omega (rpm).
On the outer ring acts a radial load (force) that i've modeled in static analysis with a pressure directed on the outer surface: now i need to investigate dynamic behaviour, so how can i apply...
Hi
by reading abaqus documentation, i've understand that hertz contacts are suitable of substructuring: what isn't clear for me, is how i can define the substructure in the case of a roller bearing.
i.e Should i "break" the inner ring, removing the "contact zone" and leaving only the part not...
Hi
i'm working with the simulation of a back up roller bearing: the load had a nominal value and a max value:
Nominal = 205KN
Max= 650KN
The material has been characterized in elastic and plastic behaviour (Elastic-->E,poisson; Plastic-->isotropic, with 4 point of stress-strain curve).
I...
It's the first time i get this warning:

Hi all
does anybody know how to get aisi 52100 fatigue data?
I need to investigate by fem (ABAQUS) the fatigue life of a rolling bearing, crack propagation also (ratcheting), but i can't find more than the usual steel makers data: E, poisson, strainVSstress etc...

Hi
i'm trying to simulate the behaviour of a backuproll under radial load, to undestand the forces distribution on the roller (taking into account outer ring deflections and deformation).
I got error like:
***WARNING: SOLVER PROBLEM. NUMERICAL SINGULARITY WHEN PROCESSING NODE RULLO-1-RAD-4.36...
I've to model a gearbox in the transitory (acceleration) and in the stationary (constant speed) running: i'm not sure abut the kind of step to use.
I'm gonna find contact pressure and stress in both case.
What about using static step for both?
I've modeled a couple of cube with contact between them. The upper cube is forced down by a force applied to a reference point, and the rp is connected to the upper surface of a cube by a kinematic coupling. Simple, but it doesn't work!
I suppose the problem is in load, because if i use...
Hi,
it's second time i post because of this problem: sorry, but i can't solve it.
I've model a single roll between a portion of inner and outer ring: on outer, the distribution is ok (figure one) but on inner isn't ok.
So i tryed with submodeling, to get some more omegeneous mesh element, but...
I've see that in some analisys, last time increment in .msg isn't equal to one, even if i set my time period to 1.
In my analisys there isn't time dependence for material or load (static hertz analisys).

HI all!
I've submitted an MPI submodeling analysis through abaqus/CAE, and I get this error:

Hi, i really don't know why, but i can't get a submodeling analisys to an happy end :(
Pre.exe started, but then i get and error (in .log file):

Hi all,
i'm trying to evaluate the mean life of a roller bearing.
In order to have a first evaluation of the outer ring deformation (that could let me simplify the analisys by simmetry, infact the bearing works like a wheel) i've created a simple model composed only by the inner/outer ring...
Does any of you saw this message? I can't understand!
