Single cylinder Balancing
Single cylinder Balancing
(OP)
Hi there
Very sorry for this , I posted this already butfor some reason could not open the reply someone sent.
I have a single cylinder motorcycle engine . What I want to do is get an estimate of the frequency and loads ..the operating range is between 2000 and 4000 rpm
for the frequency I was thinking of using
f=(1/2) (pi) (48EI/M L^3)^(1/2)
then for the Force
F = M x ( 2 pi N)^2
then find the RMS of this
Vrms = ( sum aplitude x sum frequency ) ^(1/2)
Am I anywhere near the ball park...
hope some one can help as I will then get a good Idea of a balance factor ..I hope
Regards in advance Stephen

RE: Single cylinder Balancing
Unfortunately the subject of engine balance and the various formulae for calculating it would be difficult to present in this format. Look into purchasing a copy of The Internal-Combustion Engine in Theory and Practice Volume 2 Revised Edition by Charles Fayette Taylor. Or some other equivalent book.
Good Luck
