MDO help

I need to calculate torque/force acting on the outer friction disc.

The inner friction disc rotates alongwith the shaft and the outer friction disc only rotates when it comes in contact with the inner disc. (Basic principle of clutch)

I'm not sure how to constrain the outer disc in such a way that it rotates due to friction and not as a part of the rest of the assembly.

Also, is it possible to calculate heat generated due to friction??

Please help!!

Regarding the constrains, one posibility is to work with relative speed instead of absolut ones. Consider that when the relative speed between the discs are zero, both become synchronized.

The heat generated may be calculated by the energy generated

E=[I1 I2 (w1 - w2) ^2] / 2* (I1 +I2)

A very good reference is "Mechanical Engineering Design", Shigley & Budynas

Hope it was usefull
