Analysis of moving objects

[ksarita20]

hi ,


i have problem, which i donn whether pro/mechanica can solve it.


a normal load is applied on a moving object.


i have to estimate the heat generation at the interface taking the frictional force into consideration.


Can this problem be solved using pro/mechanicaa, if not what can be a possible approximation for this.


please help me out.


thanks

hi ,


why arent anyone helping me out !


Please guide me.

Sarita,


I don't think you need MECHANICA for this analysis. You can use conservation of energy and use friction as a nonconservative force that is converted to heat. This assumes that the normal force is constant as is applied to the moving body.


Energy In (initial velocity)= Energy dissipated (friction)+Energy Out(Final Velocity)


The energy dissipated will tell you how much energy was converted to Heat.

hi Luis,


Ya i am prety sure about the analatical concept, but is there a way that i can show it pictorially, i.e the heat generation contors.


i am basically doing transient thermal analysis on disc brakes.


So what can be the possible approach for this problem.


THank in advance

Well.


Sure you can do that. If from you analytical model you can derive the heat of rate generation due to the friction then value can be applied to a surface region representing the contact area between both of the parts.

hi luis,


yaa thats what my plan is ,


Recently ilearnt how to assign a time varing temperature only by using an table option. but i would like to specifiy the Q with respect to temp in a equation form.
