Mass Spacing Equations from Dynamic Seminar 4 - 05/01/14 07:08 AM
Hi I had went through Dyanmic ansys seminar video 1 - 4, I found maximum span between node points equation given by John Lin and Adolph Molin in Video 4 is L=9.2(D^3t/w)^1/4 at 20:27,
but it given in Video 1 is L=(9.2*D^3t/w)^1/4,
Which one is correct because I dont have referece paper On Mass-Lumping Technique for Seismic Analysis of Piping” - John K. Lin & Adolph T,
another question is mass spacing calculator using equation
L^2 = k^2*(n*pi())^2/(2*pi()f)*(EIG/w)^0.5
I found mass calculator equation result will be slightly larger than John Lin equation, which equation you prefered?
