HST disc brake investigation progress note 1 thermal analysis of HST power car disc brake using a newpac axisymmetric model (IM-EST-021)

In 1977, we looked at the temperatures in an HST Power Car disc and wheel and the resulting stresses in the wheel when braked to a stand from 200 kph, to show the effect of transferring some of the braking effort from the discs to the wheel tread (Ref. 1).
