stress due to external loads of truck accelerative force
stress due to external loads of truck accelerative force
(OP)
I am conducting the stress calc for vessels on highway truck. Is there someone know how to deal with the external loads by accelerative force applied at the support of vessel. Can I apply the WRC 297 or 107 on this case?
Thanks a lot!

There's a lot of info on Railroad tank car design in the DOT sections http://www.access.gpo.gov/nara/cfr/waisidx_02/49cfr179_02.html
Maybe there's something similar for trucks somewhere?

Can you give more detail information about this methods?

Fv = 1.4g (or maybe in m/s²) then the equation should be 5000kg x 1.4g. For better understanding, you have to refer to pressure vessel handbook regarding saddle design or any L.P Zick reference. Hope this will help.

-horizontal accelerative force=0.35 times vertical reaction
-vertical accelerative force=0.35 times vertical reaction
-lateral accelerative force=0.2 times vertical reaction
I conducted the approximate stress calculation at the midspan of vessel and the area near the support, there are some high stress points. I am not sure if my calculation methods are valid. Is there some persons know the exact solution of shell stress calculation for this case? Please contact with me at wzhang@arneng.ab.ca ,Thanks!
