hello i have a SS tube (10000mm dia 25.4mm thick 1 250mm high)
i would like to see shrinkage if temp drops from 20 to -70 celc.
is it possible with SW sim to see the final result?
would it be possible to see the time it would take to reach -70 is i coulld tel that that that and that surface are in contact with dry ice?
thanks
i cant seem to be able to select initial temp it's always greyed out
Do you have a transient analysis?
i have access to sw2013 premium, study types i have thermal and of course static. in static i have a temp option as in thermal... i dont see any transient analysis or it's well hiden!
if you only have solidworks premium the only option that you have is to apply temperature boundary conditions.
so set the zero strain temperature
apply body temperatures (if you apply face temperatures it will not work well)
and find out the change in shape based on that temperature difference
initial temp is grey out all i can enter is temperature... am i doing this wrong?
As I mentioned previously, that feature is greed out unless you have a transient thermal analysis.
so i need to do static analysis or temperature?
how do i set zero strain temp?
sorry im not too familiar with this :S
hi pascal, first thing i'd do is go through the tutorials and the help just to get a better handle on the different study types...etc
as i mentioned above there are several diferent was to setup and run this analysis, you are limited by your solidworks prem license
in solidworks premium you can do static analysis only
for your purpose, you can apply a temperature boundary condition to the parts and they will expand or contract based on their CTE and the differential on temperature
this WILL NOT show you how the size changes over time as the pressure drops, this requires sim pro or higher
Pascal,
You don't need any kind of simulation to find the change in dimension of an unconstrained part due to a change in temperature. All you need is the Coefficient of Thermal Expansion for the material, the dimension and the change in temperature. The change in the dimension is the dimension times the CTE times the change in temperature.

To set the reference temperature, right click in the study, select the thermal properties tab and set the ref temperature there.
yep,
simple > static analysis with a temperature difference
medium > nonlinear, changing temperature boundary conditions
harder > time dependent thermal import into a nonlinear analysis
you'll need sim prem for this
you'll need the second analysis if you need to find out how long it takes to get down to that temperature.
