Hello
I am trying to visualize on a graph, the reactions at the level of the bearings of a crankshaft. I would like to include the reactions due to the rotation of this crankshaft.
Do you know if it is possible to do this on solidworks simulation?
Thank you.
On the basic module in statics you will only have the forces and constraints at the moment T (but good luck 1) determine and 2) represent the forces applied by the different connecting rods..).
On the more advanced (and much more expensive) simulation modules, it may be possible to make it calculate a whole cycle (but then it is probably necessary to represent the connecting rods and pistons, at least with simplified models). The inertia is also far from negligible in this kind of problem so it will all depend on the rotation frequency of your crankshaft (if we consider that the forces on the pistons are always the same, which is certainly not the case because it depends on the pressure/back pressure in the combustion chambers).
If you're not looking for constraints but just efforts, it's Solidworks motion that you should use.
There is a way to take a state of motion to calculate it in simulation. See for example: https://www.solidworks.fr/sw/images/content/Training/Motion_Instructor_Guide_2010_FRA.pdf
Good luck
Hello froussel,
Thank you, that's what I thought.
I would still like to see the efforts at the level of the levels. On the other hand, I don't know how to proceed, I did a motion analysis but I can't define the elements of the graph for the result:
If you don't put the other pieces, motion won't give you much...
It's by adding the pistons and connecting rods that motion will allow you to calculate the forces generated on your bearings (and on the pistons you have to consider a force curve corresponding to the compression, the explosion (and possibly one for the exhaust) or what happens at the top of the piston as a function of time).
In fact I left the bearing rings in contact with the crankshaft axis, so I have three parts.
The crankshaft is driven by an electric motor.
I added the maximum engine speed, the loads on the bearings and the contacts between the three elements.
The animation is generated but that's all I can get. :/
