Good Day All,
Does Pro/e Mechanica have the ability to determine force required to assemble 2 parts with a pressfit?
Looking to determine the Press tonnage require to assemble 2 parts that have a complex profile and an interference fit.
Goal would be to use a displacement constraint to move one part into the otherpart in it'sfinal assemble state and then
have it report back what press tonnage would be required to assemble the 2 parts.
Trying to bypass the hand calculations.
Can this be done and if so how?
Thanks for any help you can provide,
Randy & Chris,
where f=friction coefficient
Pc=contact pressure between the two members
d= nominal shaft dia
L=length of external member.
Pa= axial force required to interference fit
to calculate Pc for a given interference use the formula:-
where x = total interference
Dc=dia of shaft
Di = dia of inner member(this is zero for solid shaft)
Do= outside dia of collar
Uo=poissons ratio for outer member
Ui=poissons ratio for inner member
Eo=modulus of elasticity for outer member
Ei=modulus of elasticity for inner member
This formula for Pc will simplify if the materials are the same.
