Belleville washer spring model
Belleville washer spring model
(OP)
Hi,
I'm doing research work for Renault on clutches and I need the force equation of the Belleville spring for monodisk dry clutches; something like Fplate= f(X1, Xplate) where X1 is the position of the "fingers" of the spring (i.e. where the actuator pushes)
Thanks!!

I agree with arnoldh. You wan't get a constant force over the whole deflection with a belleville washer.
Did you have find a solution ?
If not I can support you with a calculation program.
For a clutch application they normally take a proportion with 1,4 for free height ho to thickness t.
RE: Belleville washer spring model
What I meant that a belleville spring with h/t=1.41 has a range of a "constant" force vs deflection (from both sides of its "Flat loaded position" . A clutch that uses a belleville spring that is loaded to the end of this range will display "constant" force as long as the spring deflection is within this range. So as long as the wear of the clutch disk is within this range the force will stay "constant". The size of this "constant range" depends on the belleville design.
