Simulate the thermo-mechanical regime for a brake mechanism

A 3D model of the disc and pads were made in the DiskBrake file (I only made the components forms). The disk is pressed from lateral sides by the brake pads. The brake pads are formed of two components tied each other – the pad (who enters in contact with the disc) and the back plate (which is pressed from outside with a pressure of 1(one) MPa.)

The brake process starts when the brake pads enter in contact with the disk (so they are pressed on the disc surface with the pressure mentioned earlier), so the frictional forces cause deceleration and heat.

The initial angular velocity of the disc is 92 rad/s and at the end of the process is 0 rad/s (see Table3). Total time for the friction process is about [url removed, login to view] seconds.

The disc is rotated so that the heat is generated by friction.

The problem is to obtain a thermal regime for two possibilities:

1st the brake process with no air flow;

2nd one by taking in count the air flow (the speed at the beginning of the process is 100 km/h (see table3)).
