Skid supported at multiple points
Skid supported at multiple points
(OP)
Hi there!
Would some one give me a hint on how to tackle this issue?
Have a skid of about 40' long that is supported on 14 (7 each side) vibration isolators. The supported unit weighs about 130,000 lbs. Isolators have equal space through out the skid length. CG is at 15' from the left.
Here is the question:
Can loading on each isolator be calculated? Or this is an indeterminant matrix? What about estimating? Is there a known method?
^-----^-----^-|----^-----^-----^-----^
...................CG 15'..........................40'
Thanks

Can you assume that the base and the skid are rigid? If so, you can assume the skid sinks down at each end by some value. The compression of each shock mount would be a linear function of its location from the end.

All of examples & formulae are for simply supported beams.
I have one equation and 14 unkowns.
Any reference to a specific edition or page number?
