This is the second year running that my MOT failed for this and it was obviously fixed last year, i know nothing about cars but can anyone tell me if there is anything specific that can be done to stop this failure happening each time?
(edit: oops missing question mark in title)
My plan:
- Grab model of joint from internet
- Recreate the results of known experiments so I know the model is accurate
- Simulate liquid in joint
- Get data (the amount of force required to operate the joint with liquids at different viscosities)
I'm completely new to ANSYS. What issues will I face? Which particular ANSYS program should I use?
Also, if I am unable to recreate the results of known experiments, how will I know the correct way to tweak my model to increase accuracy? I have a month to do this.

Just seeing those photos I couldn't quite picture it. But this makes it clear:

Amazing.
Happy ending for its designer:
> The novel feature of the coupling is the method for geometrically constraining the pair of cardan joints within the assembly by using, for example, a spherical four bar scissors linkage (spherical pantograph) and it is the first coupling to have this combination of properties.[19]
> The coupling earned its inventor, Glenn Thompson, the Australian Society for Engineering in Agriculture Engineering Award.
I've tried googling, no luck. Why exactly would you use two U-joints together vs one Rzeppa joint vs a Weiss joint? Do they have different accuracies of homokinetic transmission of force or anything like that? There are probably obvious differences regarding wear and tear and all that, but assuming the joints are perfect, are there any important differences between them?
