I was wondering if anyone could help me with a report I have been set.
I am required to find out the dynamic forces that a typical formula 1 conrod undergoes and how these forces affected by engine speed, reciprocating mass, stroke and ratio between conrod length and crank radius.
Any help that you can provide would be excellent!
I can't give the exact answer. But your question here is what the powertrain design engineer do in the early stage of the conrod design, to basically size the conrod as well as its small end and big end bearing, shank cross section size etc..
Basically, the thing to do after the geometric and inertia of the component has been determine is to estimate the cylinder pressure. This will then give you the force on the conrod for a given crank angle.
This should provide the clue in looking for the related equation typically used in classical method in sizing up the conrod. I'm quite rusty with the formula as I have left my powertrain CAE engineer job for almost year now!
