Form formula (3) can be seen clearly that the lateral offset of wheelset is proportional to the wheel diameter difference, and is inversely related to the wheel tread equivalent conicity
. The bigger the wheel diameter difference, the greater the wheel/rail longitudinal creep force, so is the wheelset yaw angle.

Goodall and Iwnicki proposed a new method to assess the vehicle stability which mainly refers to the equivalent conicity
between the wheel and rail contact .
