Dear list:

Desperately I'm trying to build a swept-sine displacement-history for
dynamic FE calculations. What I want to do is impose a sine-like
dispalcement in a fequency range from 10 to 50 Hz during one single
calcualtion. I found the following fomular for swept-sine inputs:

y(a,b,c,d,x)=c*sin{PI/(b-a)*[((b-a)*x/d+a)^2-a^2]}

What do the parameters a,b and d represent? Can anybody enlighten me? At
least I know what c is for :)

Kind Regards,

Arno
