Hello I have created a v12 engine parts and assembled them together to make a fully functioning engine. I was wondering if there is any way to simulate the explosions that take place inside and power it?
No, you won't be able to directly simulate the detonation of the air-fuel mixture; that is an incredibility complex simulation and very few software packages can do it. You could probably simulate the rigid body motion of the entire engine due to a time-dependent force via SW Motion, but you'd just need to come up with the time-dependent force for the detonation.
If you knew what the pressure profile was might you be able to put that in as a variable pressure? It appears that you can input a pressure that varies with time either linearly or a curve if you do a Linear Dynamic study.
I think the OP wants to simulate the motion of the engine, so a linear dynamic analysis wouldn't work. The only way this could potentially be handled from a FEA standpoint would be to do a non-linear dynamic simulate.
What if you kept the piston to roller/slider constraint and turn on the large displacement switch? Along with pin connections you might at least get a half turn before reaching a singularity.
Large displacement is a non-linear phenomenon.
Not sure where the FEA was inferred from the OP's post.
Isn't the design intent to apply force to the top of the piston dependent on the position of the piston/crank shaft?
Force magnitude varies and time applied.
My guess is the OP would be happy with constant force turned on and off at appropriate timing.
I think I would start with a single cylinder engine rather than a v12.
The OP didn't meantion FEA at all; nor did I for that matter (with respect to my original response). My comment about simulating this from a FEA standpoint is based off of James' suggestion to use linear-dynamics (which won't work for a number of reasons).
At this point, no one other than the OP really knows what he wants from a solution standpoint; the answer to that question defines how one should (or could) proceed.
as everyone else has requested, what are you trying to learn in this analysis?
