Valve Support Modelling - 09/22/11 12:43 PM
Hi all,
This is my first post on this forum, as i am fairly new to Caesar.
Within a closed loop piping system, i have modelled several valves as rigid elements, with a representative mass assigned. These valves are to be supported by brackets which fit to the bolting flanges of the valve, (the valve is a 3 piece isolation ball valve). The brackets are fitted to a base which is then located on a sliding bearing surface.
I have applied 2 +Y supports to each valve, one at the inlet and one at the outlet of the valve. On some of the valves, i am getting lift-off at only one of the supports, i.e. the pipework is pivoting about the support.
My concern is that the two pipe supports are not linked together in the caesar model, whereas in reality they are connected to the same base plate.
Should i simply model these supports with a single support on the valve midpoint?
Any help will be appreciated
