Thermal Load

[Anonymous]

I am trying to apply an 80 degree thermal load to the upper surface of an RC Shell but it won't let me specify a temperature in the "surface > thermal loads" window. I can assign a gradient and apply it to the shell but no temperature.

Hi

I hope this capture also will help you

Thank you for your answer. I have just a last question. If the gradient is the diffrence between top an bottom for example if T1 = 40° and T2 = 10° C. How to estimate de initial temperature (assembilng temp) ?

Initial temp is temperature let say on site while assembling \ building structure.

ok ! thanks

salut,

je veut juste savoir comment on calcul le gradient et comment l'introduire dans RSA?

et c quoi le gradient et c quoi le dt1 ?  et merci

salutations

Hi @Anonymous we have a forum in french : Robot Structural Analysis - Discussion en français

Initial  temp. = 20 c

(Maximum temperature )Summer temp. = + 45 c

(Minimum temperature )Winter temp. = - 5 c

Minimum thermal gradient ,ΔT= (-5-20) = -25 c

Maximum thermal gradient ,ΔT=(45-20) = + 25 c

The meaning of "gradient" in robot temp panel load is the temp difference between top and bottom layers of panel (difference along panel thickness)

so in your case(s) (I understood the whole panel has the temp +45 or -5 along thickness)

1. Summer : load window setings : Temperature = +25, Gradient = 0.

1. Winter :  load window setings : Temperature = -25, Gradient = 0.

Hi dear@Rafal.Gaweda

i need to know, if i understand in this case :
in summer dt =+5°c   not +25°C.
in winter dt=+5°c   not      -25°C  .
because assembling temperature is 20°c so :
in summer 45-20-20=5°c
in winter -5-20+20=-5°C

its correct or not?

thank you.
