During braking, the thermal gradient set up over the brake disc from the disc periphery down the bell to the mounting flange causes the disc to undergo undesirable distortions, termed ‘coning’. By proper design of the bell, this coning can be minimized, but, in so doing, there is a risk of high stresses occurring in the bell. In this paper, a numerical method of designing the bell to minimize coning and calculating the stresses in the bell is described. Comparison of results with standard analytical solutions shows that good agreement is obtained. An example of brake disc design and stress analysis by this method is given.
